of various alkynyl(vinyl)silanescontaining two alkynyl groups with 9-borabicyclo[3.3.1]nonane (9-BBN) proceeds by regioselective 1,2-hydroboration of the vinyl group in the first step, followed by two intramolecular 1,1-organoboration reactions to afford 1,6-disilapentalene derivatives, fusedsilacarbacycles with a siloleunit. Similarly, the analogous reaction of an alkynyl(allyl)silane gives a 1
