Abstract

Abstract Readily available air-and moisture-stable dimeric chloro-bridged CN-, CS-and CP- cyclopalladated complexes with the (sp 2) C–Pd bond react with 4.5 equiv. of KPPh 2 in THF to give the corresponding P, N-, P, S-and P, P-bidentate ligands in 35–63% yield. The phosphination method is applicable to five-and six-membered palladacycles derived from (S)-N, N-dimethyl-1-phenylethylamine,(S)-4-tert-butyl-2-phenyl-2-oxazoline, benzyl methyl ...
