摘要: The reaction of various alkynyl(vinyl)silanes containing two alkynyl groups with 9-borabicyclo[3.3.1]nonane (9-BBN) proceeds by regioselective 1,2-hydroboration the vinyl group in first step, followed intramolecular 1,1-organoboration reactions to afford 1,6-disilapentalene derivatives, fused silacarbacycles a silole unit. Similarly, analogous an alkynyl(allyl)silane gives 1,7-disilaindene derivative. products were characterized multinuclear magnetic resonance (1H, 11B, 13C and 29Si NMR) solution cases X-ray structural analysis solid state.
