Abstract

The effective catalytic activity of hydrostannation of internal and terminal alkynes has been developed by using aluminum complexes. A novel aluminum complex L¹AlMe₂ was synthesized and characterized. N-coordinated aluminum complex LAlH₂ was chosen to be the most desirable catalyst. Under relatively mild and solvent-free conditions, excellent yields, regio- and stereoselectivities have been achieved. Possible mechanistic pathways for the formation of major products by hydrostannation of alkynes with HSnBu₃ were proposed.
