Ni, Co, and Mo-metal-catalyzed alkynes hydrostannations using Bu(3)SnCl/PMHS/KF/18-crown-6 as an in situ Bu(3)SnH source.
A number of terminal alkynes were subjected to nickel, cobalt, and molybdenum catalyzed hydrostannations in presence of tributyltin chloride, polymethylhydrosiloxane, potassium fluoride and 18-crown-6 as an situ organotin hydride source to produce vinylstannanes.
