  NaOSiMe3 depended on the diphosphine ligand. Complexes 6 and 7 gave PAMP−BH3 (1) and Pd(0) species; no intermediates were observed. With 3, the intermediate Pd(dppe)(o-An)(P(Me)(Ph)(BH3)) (10) was observed by 31P NMR, while 4 gave the isolable diastereomeric palladium complexes (SP)-Pd((S,S)-Chiraphos)(o-An)(P(Me)(Ph)(BH3)) (11a) and (RP)-Pd((S,S)-Chiraphos)(o-An)(P(Me)(Ph)(BH3)) (11b), whose absolute configurations

  The heterobimetallic complexes [MPd(PPh3)(Cequivalent toC-Ph)(CO)(3)(eta(5)-C-5-C5H2Ph2(PPh2)] (5a, M = Mo; 5b, M = W) convert under chromatography to diastereomeric mixtures of the new trimetallic clusters [PdM(CO)(3)(eta(5)-C5H2Ph2(PPh2)}(2)] (M = Mo, 9a; W, 9b), which contain a linear M-Pd-M array clamped between two (diphenyl)cyclopentadienyl-diphenylphosphino ligands. Diastereomeric pure forms of both trimetallic clusters 9a,b were obtained by fractional crystallization procedures, and the molecular structures of rac-9a and rac-9b were determined by single-crystal X-ray diffraction analyses. The trimetallic complexes 9a,b have been found to be intermediates in coupling reactions between M-I moieties and Bu(3)SnCequivalent toC-Ph, to form metallacetylides M-Cequivalent toC-Ph. Independent high-yield synthetic routes to 9a,b have been developed.
• Air-Stable, Recyclable, and Regenerative Phosphine Sulfide Palladium(0) Catalysts for C−C Coupling Reaction

  Mononuclear phosphine sulfide Pd(0) complexes and a polymer-supported triphenylphosphine sulfide Pd(0) complex were prepared as new air-stable Pd(0) catalysts for C-C coupling reactions. The phosphine sulfide Pd(0) complexes are not decomposed after completion of Suzuki-Miyaura coupling, and the polymer-supported Pd(0) catalyst is practically recyclable, while phosphine Pd(0) complexes are decomposed into inactive Pd(0) black after consuming the substrates. New catalytic activity of Pd(0) that promotes chalcogen atom replacement of phosphine chalcogenides (R3P=X, X = O, S, Se) is reported. A mechanistic study revealed that the new catalytic chalcogen replacement results from activation of the P=X bond as well as promotion of the oxidative chalcogenide formation. The intermediate phosphine was successfully trapped as a phosphine Pd(II) complex, and the P=X bond activation is applicable to regeneration of phosphine or phosphine sulfide from oxidized phosphine.
