Synthesis and characterization of CuI/AuI complexes derived from monothiocarbonate and tertiary phosphine ligands

The reactions of K{S(O)COR} (R?=?iPr, iBu) with Cu(CH3CN)4PF6 / Au(THT)Cl and PPh3/dppf in stoichiometric ratios afford the compounds Cu{S(O)COiPr}(PPh3)2 (1), Au{S(O)COiPr}(PPh3)2 (2), [Cu4{S(O)COiBu}3(PPh3)6]+ (3), Au{S(O)COiBu}(PPh3)2 (4) and Cu{S(O)COiPr}(dppf) (5) quantitatively. The complexes are characterized by the combination of elemental analysis, IR, 1H, 31P NMR, mass spectrometry (1, 2), cyclic voltammetry (5) and single crystal X-ray techniques. In all of the monomeric complexes, CuI and AuI possess tricoordinate trigonal planar geometry but in 3, three copper atoms adopt tetrahedral coordination geometry and the fourth copper atom is trigonally coordinated. A mono-dentate binding mode through sulfur atom [ROC(O)S?] is observed for the ligands in all the mononuclear complexes. Interestingly in 3 a bridging mode (kappa3: mu2-S, mu-O) has been observed for the first time in monothiocarbonate chemistry. Complexes 2 and 4 show prominent luminescent behavior emitting bluish green at 472 and 467?nm, respectively, in solid state at 77?K. In fact these are the first examples of any monothiocarbonate complexes exhibiting photoluminescent behavior. Further an unexpected gold sulfide complex Au4S2(PMe3)4 (6) formed probably via the C[sbnd]S bond scission of monothiocarbonate ligand has also been reported.

Sequential treatment of [M(CO)6] (M = W, Mo, but not Cr) with 1 equiv of LiNiPr2, iodine, and PPh3 provides [M(eta2-OCNiPr2)I(CO)3(PPh 3)], which serve as precursors for a wide range of bidentate carbamoyl complexes; however, if for M = W, an excess of LiNiPr2 is employed, the aminomethylidyne complex [W(?CN-iPr2)I(CO)3(PPh3)] is also obtained.

OsXCl(phosphine)2(diamine) and OsXCl(diphosphine)(diamine) (X = Cl, H) Complexes for Ketone Hydrogenation

The osmium complex trans-[OsCl2(PPh3)2(en)] (2) was prepared by reaction of [OsCl2(PPh3)3] (1a) with ethylenediamine (en), whereas the diphosphine derivatives trans-[OsCl2(dppf)(NN)] (NN = en (3), bn (4; bn = 1,4-butanediamine)) and trans-[OsCl2(dpbp)(en)] (5) were obtained from 1a, dppf or dpbp, and the corresponding NN ligand in CH2Cl2 or toluene. An X-ray diffraction study has been provided for 3. The isolation of the chiral derivatives trans-[OsCl2(diphosphine)((R,R)-dpen)] (diphosphine = dppf (6), dpbp (7), (R,R)-skewphos (8)) was achieved by reacting 1a with the diphosphine and (R,R)-dpen in toluene. Treatment of the precursor [Os2Cl4(P(m-tolyl)3)5] (1b) with en afforded [OsCl2(P(m-tolyl)3)2(en)] (9), while reaction of 1b with dppb and N,N-dmen gave [OsCl2(dppb)(N,N-dmen)] (10). The chiral derivatives [OsCl2(diphosphine)(NN)] (11-21; diphosphine = (S)-MeObiphep, (R)-MeObiphep, (R)-xylMeObiphep, (R)-binap, (S)-xylbinap, (R)-xylbinap, (R,S)-Josiphos NN = en, (R,R)-dpen, (R)-daipen, (R,R)-dppn) were prepared from 1b and the corresponding diphosphine and NN ligands in toluene. The monohydride trans-[OsHCl(P(m-tolyl)3)2(en)] (22) was synthesized by reaction of 1b with H2 (1 atm) in the presence of NEt3, followed by addition of en in toluene. Similarly, trans-[OsHCl(dppf)(en)] (23) was synthesized from 1a, H2, and NEt3, followed by treatment with dppf and en. Complexes 2-5, 9, 10, 22, and 23 efficiently catalyzed the hydrogenation of acetophenone with H2 under low pressure (5 atm) at 60-70 C in ethanol (1-2 mol % of NaOEt) with the ratio S/C = 5000-10000. The chiral derivatives 6-8 and 11-21 afforded the asymmetric hydrogenation of acetophenone with up to 90% ee by combining bulky xylyl-substituted MeObiphep or binap-type ligands with (R)-daipen or (R,R)-dpen ligands. Catalytic transfer hydrogenation of acetophenone was observed with 3, 6, and 7 (S/C = 2000) in 2-propanol and in the presence of NaOiPr (2 mol %) at 60-82 C.

This report describes a new palladium catalyzed synthesis of 4-cyano-1,10-phenanthroline (nphen, 1), 4,7-dicyano-1,10-phenanthroline (dnphen, 2) and their corresponding ruthenium complexes. The two cationic complexes, [(tbbpy)2Ru(nphen)]2+ 3 and [(tbbpy)2Ru(dnphen) ]2+ 4 (tbbpy = 4,4?-di-tert-butyl-2,2?-bipyridine), were synthesized using an improved microwave procedure. All compounds were fully characterized, including the solid-state molecular structures of the complexes. The influence of 1 and 2 on the metal-to-ligand charge transfer (MLCT) transitions were studied and compared to the ruthenium(II) polypyridyl complexes containing the related 4,4?-dicyano-2,2?-bipyridine (dnbpy) and the non-functionalized 1,10-phenanthroline (phen) ligand.

Sterically controlled reactivity of palladium(II) tetranuclear cyclometallated complexes. Crystal and molecular structure of the novel tetranuclear compound [Pd2{1,3-[C(H)=NCH2C4H7O] 2C6H2}-(mu-Cl)(Cl)(PPh3)] 2

The reaction of the Schiff base ligands 1,3-[C=N(H)CH2C4H7O]2C 6H4 (1) and 1,4-[C=N(H)CH2C4H7O]2C 6H4 (14) with palladium(II) acetate in toluene gave the acetato-bridged cyclometallated compounds [Pd2{1,3-[C(H)=NCH2C4H7O] 2C6H2}(mu-AcO)2]2 (2) and [(mu-AcO)Pd{1,4-[C(H)=NCH2C4H7O] 2C6H2}Pd(mu-AcO)]n (15). Reaction of 2 and 15 with aqueous sodium chloride gave the chloro-bridged cyclometallated compounds [Pd2{1,3-[C(H)=NCH2C4H7O] 2C6H2}(mu-Cl)2]2 (3) and [(mu-Cl)Pd{1,4-[C(H)=NCH2C4H7O] 2C6H2}Pd(mu-Cl)]n (16), respectively, after a metathesis reaction. Reaction of 3 with triphenylphosphine in a 1:2 molar ratio gave the tetranuclear complex [Pd2{1,3-[C(H)=NCH2C4H7O] 2C6H2}(mu-Cl)(Cl)(PPh3)] 2 (4), where only one of the bridging PdCl2Pd moieties was cleaved, and which was characterized by X-ray crystal structure analysis. However, reaction of 16 with PPh3 gave the dinuclear complex [(PPh3)(Cl)Pd{1,4-[C(H)=NCH2C4H 7O]2C6H2}Pd(PPh3)(Cl)] (17) after a full bridge-splitting reaction. Similarly, treatment of 3 with PMe2Ph, pyridine and thallium acetylacetonate produced the dinuclear complexes 5, 6 and 7, respectively. Treatment of 4 with pyridine in a 1:2 molar ratio, and with 4,4?-dipyridyl in an 1:1 molar ratio, gave the di- and tetranuclear complexes 12 and 13, respectively. Reaction of 3 with the tertiary diphosphine cis- Ph2PCH=CHPPh2 in a 1:2 molar ratio yielded the tetranuclear complex [Pd2{1,3- [C(H)=NCH2C4H7O]2C6H 2}(mu-Cl)(Ph2PCH=CHPPh2-P,P)][Cl] 2 (8) after selective splitting of one of the PdCl2Pd bridging moieties. However, reaction of 3 with cis-Ph2PCH=CHPPh2 and Ph2P(CH2)2PPh2 in 1:4 molar ratios gave the dinuclear complexes 9 and 10, respectively. Reaction of 3 with the diphosphine Ph2PC5H4FeC5H4PPh 2 in a 1:2 molar ratio yielded the trinuclear complex [Pd2{1,3- [C(H)=NCH2C4H7O]2C6H 2}(mu-Ph2PC5H4FeC5H 4PPh2)] (11), with the diphosphine bridging the two palladium atoms of the dicyclometallated moiety.

One-pot synthesis and the X-ray structures of rhenium(I) diphosphine hydrides, fac-(CO)3(P-P)ReH [P-P = dppp, dppb, and dppfe]

Rhenium(I) tricarbonyl (diphosphine) hydrides have been synthesized in high yield from one-pot reaction of Re2(CO)10 with diphosphines in refluxed pentanol. The reactions of Re2(CO) 10 with chelated diphosphines, P-P, where P-P are 1,3-bis(diphenylphosphino)propane (dppp), 1,4-bis(diphenylphosphino)butane (dppb), and 1,1?-bis(diphenylphosphino)ferrocene (dppfe), in refluxed 1-pentanol or 1-hexanol afford the corresponding hydrides 1-3 fac-(CO) 3(P-P)ReH, (for 1, P-P is dppp, for 2, P-P is dppb, and for 3, P-P is dppfe) in high yield. The hydrides 1-3 have been characterized spectroscopically and by X-ray crystal structure determinations.

Synthetic studies of permethylcyclopentadienyl ruthenium(II) complexes involving dppf, (¡À) -BINAP and (¡À) -DIOP ligands

1,1?-Bis(diphenylphosphino)ferrocene (dppf) reacted with RuCl(Ph3P)2Cp* to give RuCl(dppf)Cp* in good yield. The complex reacted with AgBF4 in acetonitrile to give [Ru(CH3CN) (dppf)Cp*]BF4 quantitatively and in acetone to give [Ru(eta2-O2) (dppf)Cp*]BF4 in good yield. The structure of the latter was determined by X-ray analysis. (¡À)-BINAP and (¡À)-DIOP were reacted with [RuCl2Cp*]n/Zn to give RuCl[(¡À)-BINAP]Cp* and RuCl[(¡À)-DIOP]Cp*, respectively, in moderate yields. They reacted with phenylacetylene in the presence of NH4PF6 to afford the corresponding RuII phenylacetylide complexes. The asymmetric condensation of phenylacetylene with allyl alcohol in the presence of these diphosphine complexes was unsuccessful.
