  Synthesis and Characterization of Trimetallic Complexes Containing M−Pd−M Arrays (M = Mo, W) and Their Relevance in Palladium-Catalyzed Metal−Carbon Bond Formation

  摘要：

  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 [Pd{M(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.

  A catalytic cycle of reaction between [eta(5)-1-(diphenylphosphino) -2,4-diphenylcyclopentadienyl]tricarbonylmetal iodides, [eta(5)-1-Ph2P-2,4-Ph2C5H2]M(CO)(3)I (1a, M = Mo; 1b, M = W), with zerovalent palladium and tributyltin acetylides affords the final acetylide products [eta(5)-1-Ph2P-2,4-Ph2C5H2]M(CO)(3)C=CPh (5a, M = Mo; 5b, M = W). This communication describes the main processes and intermediates involved in this palladium-catalyzed metal-carbon bond formation.
