The dehydrosilylation of 2-(SiR2H)-biphenyls catalyzed by B(C6F5)(3) and a weak base forms silafluorenes with H-2 as the only byproduct. Attempts to extend this approach to synthesize siloles derived from 2,2'-bithiophenes and N-Me-2-Ph-indole resulted in competing reactivity, including protodesilylation. B(C6F5)(3) also catalyzed the one-pot, two-step formation of silaindenes from aryl-alkynes by alkyne trans-hydrosilylation, followed by an intramolecular Sila-Friedel-Crafts reaction facilitated by a weak base.
