Silylpinacolboranes bearing dialkylamino groups on the silicon atom several as synthetic equivalents of silylene in palladium-catalyzed reactions with terminal alkynes, leading to the formation of 2, 4-disubstituted siloles in high yield. It was found that the amino group on the silicon atom was critically important for the reaction; no silole products were found in reactions using silylpinacolboranes carrying aryl, chloro, or alkoxy groups on the silicon atoms. Site-selective bromination of 1,1-dimethyl-2,4-diphenylsilole followed by Migita-Kasugi-Stille coupling with (arylalkynyl)tributylstannanes gave novel Pi-conjugated siloles with good total yields.
