Kukowski, Jonathan E.; Smoliakova, Irina P. published an article on February 1 ,2019. The article was titled 《Steric and electronic effect of secondary phosphines in reactions with cyclopalladated complexes》, and you may find the article in Polyhedron.Name: Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II) The information in the text is summarized as follows:
Reactions of secondary phosphines HPR2 (b-e; R = 4-MeOC6H4, 4-CF3C6H4, mesityl, 1-adamantyl) and HPPhtBu (f) with cyclopalladated complexes (CPCs) derived from N,N-dimethylbenzylamine (1), L-fenchone methyloxime (FenchOx, 3), (S)-N,N-dimethylbenzylamine (9), and (S)-di-2,4-tert-butyloxazoline (11) were studied. Phosphination of the cyclopalladated ligands in complexes 1 and 3 was observed using either 4.5:1 or 9:1 molar ratios of HPAr2 (b,c) to CPC in the presence of 9 equiv of Cs2CO3. The corresponding N,P-ligands (2b,c, 4b,c) were isolated in 44-59% yields. Reactions of the sterically hindered HPMes2 with CPCs 1 and 3 provided the phosphine oxide (4d’), only for the latter complex (32% yield). Attempts to synthesize N,P ligands with HPAd2 were unsuccessful with either palladacycle. Major products of the reactions of complexes 1 and 3 with bulky HPMes2 and HPAd2 were either rare mononuclear complexes [(1,2-Me2NCH2C6H4)Pd(HPR2)Cl] (5d,e; up to 90%) and [(FenchOx)Pd(HPR2)Cl] (7d,e; 81 and 86%) with an ancillary secondary phosphine ligand or dinuclear monophosphido, monochloro-bridged complexes [(1,2-Me2NCH2C6H4)2Pd2(μ-PR2)(μ-Cl)] (6d, 98%) and [(FenchOx)2Pd2(μ-PR2)(μ-Cl)] (8d,e, 69% and 66%) depending on the HPR2/CPC molar ratio used. Enantiopure CPC 3 reacted with racemic HPPhtBu to give a single diastereomer of the phosphination product (4f, 12% yield). Attempts to use the racemic phosphine in transformations with two other enantiopure CPCs, to form a C-PPhtBu bond were unsuccessful. Instead, reactions of these two complexes with racemic HPPhtBu provided monophosphido, monochloro-bridged CPCs in 32 and 76% yield, resp. Anal. of 1H, 13C{1H} and 31P{1H} NMR data of all new Pd(II) complexes and N,P ligands is provided. An x-ray crystallog. study of complex 7d proved its trans-N,P geometry.Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)(cas: 18987-59-2Name: Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)) was used in this study.
Di-μ-chlorobis[2-[(dimethylamino)methyl]phenyl-C,N]dipalladium(II)(cas: 18987-59-2) belongs to organochlorine compounds. Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
