Synergy between Experimental and Computational Chemistry Reveals the Mechanism of Decomposition of Nickel-Ketene Complexes

A series of (dppf)Ni(ketene) complexes were synthesized and fully characterized. In the solid state, the complexes possess eta2-(C,O) coordination of the ketene in an overall planar configuration. They display similar structure in solution, except in some cases, the eta2-(C,C) coordination mode is also detected. A combination of kinetic analysis and DFT calculations reveals the complexes undergo thermal decomposition by isomerization from eta2-(C,O) to eta2-(C,C) followed by scission of the C=C bond, which is usually rate limiting and results in an intermediate carbonyl carbene complex. Subsequent rearrangement of the carbene ligand is rate limiting for electron poor and sterically large ketenes, and results in a carbonyl alkene complex. The alkene readily dissociates, affording alkenes and (dppf)Ni(CO)2. Computational modeling of the decarbonylation pathway with partial phosphine dissociation reveals the barrier is reduced significantly, explaining the instability of ketene complexes with monodentate phosphines.

[PF6] and [Cu(xantphos)(N^S)][PF6] compounds with 2-(thiophen-2-yl)pyridines

A series of [Cu(POP)(N^S)][PF6] and [Cu(xantphos)(N^S)][PF6] compounds (POP = bis(2-(diphenylphosphino)phenyl)ether, xantphos = 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene) in which the N^S ligand is a 2-(thiophen-2-yl)pyridine (1), 2-(thiophen-2-yl)-6-methylpyridine (2), 2-(5-methylthiophen-2-yl)pyridine (3) or 2-(5-methylthiophen-2-yl)-6-methylpyridine (4) have been prepared and characterized in solution and the solid state. Single crystal structures of [Cu(POP)(1)][PF6], [Cu(xantphos)(1)][PF6], [Cu(xantphos)(2)][PF6], [Cu(POP)(3)][PF6]¡¤CH2Cl2, and [Cu(xantphos)(4)][PF6] confirm chelating N^S and P^P ligands, and distorted tetrahedral copper(i) centres. There is close cation?anion association, particularly in [Cu(xantphos)(1)][PF6]. Although the compounds are stable over days in CH2Cl2 solution, they are susceptible to the effects of competing ligands such as chloride ion and MeCN. Analysis of the NMR spectroscopic data of a solution of [Cu(POP)(3)][PF6] with added Cl-, gives a Kd value of 0.14 ¡À 0.03 mM, indicative of ion-pairing. [Cu(POP)(N^S)][PF6] and [Cu(xantphos)(N^S)][PF6] exhibit quasi-reversible or irreversible Cu+/Cu2+ oxidations. They are blue emitters in solution, and the presence of the 5-methyl group in the thiophene ring in 3 and 4 leads to a red-shift in the emission. The highest photoluminescence quantum yields are for [Cu(POP)(2)][PF6] (30.8%) and [Cu(POP)(4)][PF6] (33.2%), both of which have a 6-methyl-substituted pyridine ring in the N^S ligand. Excited-state lifetimes are <5 ns. On going from solution to powder samples, red-shifts of 133 to 163 nm are observed leading to yellow emitters. The brightest emitter, [Cu(xantphos)(1)][PF6], was tested in a LEC device but showed poor electroluminescence and poor charge transporting characteristics.

Synthesis and Characterization of Diiron Thiadithiolate Complexes Related to the Active Site of [FeFe]-Hydrogenases

On the basis of preparation of the known complex [Fe2(mu SCH2)2S(CO)6] (A) by a new method involving condensation of [(mu-LiS)2Fe2(CO)6] with excess S(CH 2Br)2, twelve new diiron thiadithiolates as mimics of the [FeFe]-hydrogenase active site have been synthesized by substitution of the CO ligand and coordination at the central S atom of complex A with appropriate reagents. Treatment of A with 1. equiv. of the monodentate ligands PPh 3 and [(eta5-C5.H5) (eta5-Ph2PC5H4)Fe] in the presence of Me3NO and with 1 equiv.tBuNC and cyclohexyl isocyanide gave the single [2Fe3S]-cluster-containing monosubstituted complexes [Fe2(U-SCH2J2S(CO) 5(L1)] (1, L1 = PPh3; 2, L1 = (eta5-C5H5) (eta5Ph 2PC5H4)Fe; 3, L1 = tBuNC; 4, L 1 = C6H11NC), whereas the double [2Fe3S]cluster-containing disubstituted complexes [(Fe2(mu-SCH 2)2S(CO)5}2(L2)] [5, L2 = 4,4′-(Ph2P)2(C6H 4)2; 6, L2 = trans-Ph2PCH=CHPPh 2; 7, L2 = 1,4-(CN)2C6H4; 8, L2 = (eta5-Ph2PC5H 4)2Fe; 9, L2 = (eta5-Ph 2PC5H4)2Ru] were produced by reaction of A with 0.5 equiv. of the corresponding bidentate ligands in the presence of Me3NO. In addition, the single [2Fe3S]-cluster-containing complexes in which the central S atom is coordinated, [{Fe2(mu- SCH2)2S(CO)6}[(eta5-MeC 5H4)(CO)2Fe}(BF4)] (10), [(Fe 2(mu-SCH2)2S(CO)6 }{Cr(CO) 5}] (11), and [(Fe2(muSCH2) 2S(CO)6}[W(CO)5}] (12), could be obtained by reaction of complex A with the in situ prepared. [((mu5-MeC 5H4)(CO)2Fe)(BF4)], [Cr(CO) 5(thf)], and [W(CO)5;(thf)], respectively. While complex 3 was found to be able to reduce the proton of the weak acid Et3NHCl to give H2, the X-ray crystallographic study confirmed that (i) each P atom of the phosphane ligands in 1 and 8 occupies an apical position at the Fe atoms, (ii) the isocyanide ligand in 3 lies in a basal position of the Fe atom, and (iii) the (eta5MeC5H4)(CO) 2Fe, Cr(CO)5, and W(CO)5 units in 10-12 are linked to the central S atom of complex A by an equatorial bond from the two fused sixmembered rings of their [2Fe3S]-cluster cores.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 1,1-Bis(diphenylphosphino)ferrocene, you can also check out more blogs about12150-46-8

Synthetic Routes to Thiol-Functionalized Organic Semiconductors for Molecular and Organic Electronics

Over the few last decades, the potential of using thiol functionalities to induce the self-assembly of various kinds of molecules on metal surfaces has been widely demonstrated. In particular, pi-conjugated molecules can undergo self-assembly on metallic surfaces to create electroactive supramolecular layers, which have found important applications in organic and molecular electronics. For this reason, the synthesis of thiol-functionalized conjugated molecules has been the object of extensive research and many routes have been developed for their synthesis. This Focus Review provides an overview of the state-of-the-art methods for the syntheses of organic semiconductors that are decorated with pendant thiol groups for applications in self-assembly and molecular and organic electronics. Particular attention is given to synthetic strategies based on organometallic cross-coupling reactions for the preparation of compounds with extended conjugation.

Recent Progress in Pyrimido[5,4-d]pyrimidine Chemistry

The review deals with the pharmaceutically important group of pyrimido[5,4-d]pyrimidines (PPs) and covers the relevant literature published from about 1986 through 2014. A synthetic section describes the formation of PPs from pyrimidines both by cyclization to give a second pyrimidine ring and by transformation of another fused heterocyclic ring. In the structure-related section, properties such as the spectroscopic and electrochemical behavior are stressed. The reactivity of PPs is dominated by the nucleophilic substitution of chloro compounds and the formation of derivatives and analogs of Dipyridamole. This useful drug is also the main focus of the application section.

Synthesis, single crystal X-ray structure determination and NMR studies of Cp2Fe(PPh2)2PtPh2 and Cp2Fe(PPh2)2PtI2

Diphenyl[1,1?-bis(diphenylphosphino)ferrocene]platinum(II), Cp2Fe(PPh2)2PtPh2 (1) and diiodo[1,1?-bis(diphenylphosphino)ferrocene]platinum(II), Cp2Fe(PPh2)2PtI2 (2) were synthesized in nearly quantitative yield, with excellent purity by allowing Cp2Fe(PPh2)2 to react with (COD)PtPh2 and (COD)PtI2 (COD=1,5-cyclooctadiene), respectively. Compounds 1 and 2 have been well characterized by various analytical and spectroscopic techniques and also by single crystal X-ray diffraction. Platinum in both the complexes seemed to have a distorted square planar geometry. Interestingly, the respective bite angles (P-Pt-P bond angle) in 1 (101.2(1) A) and 2 (100.6(1) A) deviate from the ideal 90 situation and are larger than in the reported structure, dppfPtCl2 [dppf=1,1?-bis(diphenylphosphino)ferrocene]. A detailed NMR study, including 2D and simulation experiments has been performed on these compounds for complete structural assignment. The compounds 1 and 2 crystallized in triclinic space groups P1 and P1 with a=12.268(2) A, 10.089 (1); b=13.043(2) A, 10.856 (1); c=13.649(1), 17.787(1) A; alpha=100.49(1), 86.75(1); beta=93.12(1), 77.52(1); gamma=103.44(1), 64.91(1); V=2078.0(5), 1721.3(3) A3 and Z=2 and 2, respectively. The final refinements of 1 and 2 converged at R=0.0388 and 0.0580, respectively.
