Abstract
α-Diketones (benzil, methyl phenyl diketone, acenaphthenequinone, camphorquinone) reacted with hexamethyldisilane in the presence of a Pd or Pt catalyst (PdCl2(PMe3)2, Pt2(dba)3-P(OCH2)3CEt, etc.) to give the corresponding 1,2-bis(trimethylsiloxy)ethenes in excellent to moderate yields, while methyl benzoylformate provided dimethyl 2,3-diphenyl-2,3-bis(O-trimethylsilyl)tartrate.Keywords
