Activation of the dialkylpalladium complex (phen)Pd(CH3)2 (phen = 1,10-phenanthroline) with B(C6F5)3 affords a competent catalyst for the dimerization of vinyl silanes. All organic products of the catalytic dimerization of trialkoxyvinylsilanes were characterized by in situ NMR spectroscopy and GC-MS. The putative palladium cation was characterized by NMRspectroscopy. Upon activation, the palladium complex generated products in moderate yield (60-70%) and selectivity (~60:40, dimer:disproportionation products).
