Hydrostannation of C–C multiple bonds with Bu3SnH prepared in situ from Bu3SnCl and Et3SiH in the presence of Lewis acid catalysts
Abstract
A number of alkynes 5, allene 11 and alkene 13 smoothly underwent hydrostannation with tributyltin hydride 1, prepared in situ from tributylchlorostannane 6 and triethylsilane 7 in the presence of catalytic amounts of Lewis acids.
