Kashiwabara, Taigo published the artcileDecarbonylative Coupling of Fluorobenzoyl Chlorides with Hexamethyldisilane in the Presence of a Palladium Complex Catalyst: Extremely Facile Decarbonylation of Pentafluorobenzoyl-Pd Complex Relevant to C6F5SiMe3 Formation, Formula: C9H8F2O2, the publication is Organometallics (2006), 25(19), 4648-4652, database is CAplus.
Pd-phosphite complexes (PdCl2(PhCN)2 + P(OEt3)3 or P(OPr)3 most effective) catalyze the reaction of pentafluorobenzoyl chloride with hexamethyldisilane to selectively form pentafluorophenyltrimethylsilane as virtually the sole product. The reaction of 3,5-difluoro- or 4-fluorobenzoyl chloride was less selective, giving a mixture of corresponding benzoyl- and phenylsilanes. Oxidative addition of pentafluorobenzoyl chloride with Pd(PPh3)4 or with Pd[P(OEt)3]2 generated in situ proceeds readily, but decarbonylation occurs, giving trans-C6F5PdClL2 (L = PPh3, P(OEt)3), selectively. The crystal and mol. structures of trans-C6F5PdCl(PPh3)2 were determined by x-ray crystallog.
