4-Bromotrifluoromethyl benzene efficiently undergoes oxidative addition to palladium(0) precursors to give phosphine stabilized bromo(4- trifluoromethylphenyl)palladium(II) complexes in high yields. Exchange of the bromo and the phosphine ligands allows further derivatization of these compounds. The solid state structures of two palladium(II) complexes of the type (L-L)Pd(Br)(C6H4CF3), with L-L either performing cis or trans coordination could be elucidated.

The three-step synthesis of new mixed P/N/N?/O-donor ligands C 6H3(OH){2-NHC(O)CH2NCHC6H 4PPh2}(4-CH3) 3a·HH and C 6H4(OH){3-NHC(O)CH2NCHC6H 4PPh2} 3b·HH, by Schiff base condensation of the 1 amines C6H3(OH){2-NHC(O)CH2NH 2}(4-CH3) 2a or C6H4(OH){3-NHC(O) CH2NH2} 2b with C6H4(CHO)(2-PPh 2) in refluxing EtOH, is described. Reaction of 1 equiv. of 3a·HH or 3b·HH with MCl2(cod) (M = Pt, Pd; cod = cycloocta-1,5-diene) affords the kappa2-PN-chelate complexes MCl2(3a·HH) (M = Pd 4a; M = Pt 4b) and MCl 2(3b·HH) (M = Pt 4c). The dichlorometal(II) complexes 4d and 4e, bearing instead a pendant 4-phenolic group, were similarly prepared (in >90% yield). Chloro-bridge cleavage of [Pd(mu-Cl)(eta3-C 3H5)]2 with 3a·HH or 3b·HH gave the monocationic kappa2-PN-chelate complexes [Pd(eta3- C3H5)(3a·HH)]Cl 5a or [Pd(eta3-C 3H5)(3b·HH)]Cl 5b, respectively. Elimination of cod, and single CH3 protonation, from Pt(CH3) 2(cod) upon reaction with 1 equiv. of 3a·HH or 3b·HH in C7H8 at room temperature afforded the neutral complexes C6H3(OH){2-NC(O)CH2NCHC6H 4PPh2Pt(CH3)}(4-CH3) 6a and C 6H4(OH){3-NC(O)CH2NCHC6H 4PPh2Pt(CH3)} 6b, respectively bearing a monoanionic (3a·H- or 3b·H-) kappa3-PNN?-tridentate ligand. Amide and phenol deprotonation were readily achieved, using KOtBu as base, to give high yields of the kappa4-PNN?O-tetradentate complexes C6H 3(O){2-NC(O)CH2NCHC6H4PPh 2Pd}(4-CH3) 7a and C6H3(O){2-NC(O) CH2NCHC6H4PPh2Pt}(4-CH3) 7b bearing the dianionic ligand 3a2-. All new compounds have been characterised by multinuclear NMR, FTIR, mass spectroscopy and microanalysis. Single crystal X-ray studies have been performed on compounds 1b·1.5CH2Cl2, 3b·HH·0.5Et 2O, 6b·CHCl3 and 7b·0.5Et2O.

Depending on the conditions used, reactions of benzyldiphenylphosphine (HL1) with Na2PdCl4 on silica gel or with Pd(OAc)2 on the same absorbent followed by treatment with LiCl provide one or more of the four compounds: the cyclopalladated binuclear complex [(mu-Cl)PdL1]2 (1), cis and trans isomers of the coordination complex PdCl2(HL1)2 (3), the binuclear coordination complex [(mu-Cl)PdCl(HL1)]2 (4), and compound PdCl2(HL1)3 (5). The 56% yield of complex 1 achieved using the reaction with Na2PdCl4 and NaOAc on SiO2 is higher than that reported for the direct cyclopalladation of PBnPh2 with Pd(OAc)2 in AcOH. X-ray diffraction studies of the cyclopalladated dimer 1 and the coordination complex cis-3 are reported.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 13440-07-8, C20H15OP.

A practical approach for the synthesis of phosphinic amides via the coupling of secondary phosphine oxides (SPOs) with O-benzoylhydroxylamines has been reported. Simply heating the mixture of SPOs and O-benzoylhydroxylamines in the presence of K2CO3 gave the phosphinic amides in moderate to excellent yields under an open air system. This method provides a practical and catalyst-free method for the synthesis of various synthetically valuable phosphinic amides.

The rhodium-catalyzed, highly N2- and N1-selective coupling of benzotriazoles with allenes is reported. The exceptionally high N2 and N1 selectivities were achieved by using a rhodium(I)/DPEphos and rhodium(I)/JoSPOphos catalyst, respectively. This method permits the atom-economic synthesis of valuable branched N2- and N1-allylated benzotriazole derivatives and allows for preliminary studies of their reactivity.

Reference of 312959-24-3, An article , which mentions 312959-24-3, molecular formula is C48H47FeP. The compound – 1,2,3,4,5-Pentaphenyl-1′-(di-tert-butylphosphino)ferrocene played an important role in people’s production and life.

In spite of the wide application potential of 1,2,4,5-tetrazines, particularly in live-cell and in vivo imaging, a major limitation has been the lack of practical synthetic methods. Here we report the in situ synthesis of (E)-3-substituted 6-alkenyl-1,2,4,5-tetrazine derivatives through an elimination-Heck cascade reaction. By using this strategy, we provide 24 examples of pi-conjugated tetrazine derivatives that can be conveniently prepared from tetrazine building blocks and related halides. These include tetrazine analogs of biological small molecules, highly conjugated buta-1,3-diene-substituted tetrazines, and a diverse array of fluorescent probes suitable for live-cell imaging. These highly conjugated probes show very strong fluorescence turn-on (up to 400-fold) when reacted with dienophiles such as cyclopropenes and trans-cyclooctenes, and we demonstrate their application for live-cell imaging. This work provides an efficient and practical synthetic methodology for tetrazine derivatives and will facilitate the application of conjugated tetrazines, particularly as fluorogenic probes for live-cell imaging. Stitching probes together: The in situ synthesis of (E)-3-substituted 6-alkenyl-1,2,4,5-tetrazine derivatives through an elimination-Heck cascade reaction is reported. 24 examples of pi-conjugated tetrazine derivatives are provided, including conjugated fluorescent probes that show drastic fluorescent turn-on when reacted with dienophiles. Their suitability for live-cell imaging is demonstrated. TCO=trans-cyclooctene.

Direct access to trideuteriomethoxylated aromatic and heteroaromatic compounds has been developed. Various aryl and heteroaryl halides underwent d3-methoxylation under mild reaction conditions by using a catalyst system composed of the commercially available monodentate phosphane ligand tBuXPhos and Pd(OAc)2. Inexpensive CD3OD served as an efficient trideuteriomethoxylating agent. The simple and straightforward synthesis of labeled methyl (hetero)aryl ethers via palladium-catalyzed C-O cross-coupling reaction of (hetero)aryl halides with CD3OD was developed. The tBuXPhos ligand is used for the first time in ether synthesis. Copyright
