title: A practical one-pot synthesis of vinylstannanes from ketones.
abstract: Treatment of ketones with Bu3SnLi followed by addition of MsCl/Et3N to the resulting alkoxide provides vinylstannanes. Cyclic vinylstannanes are particularly amenable to this procedure and isolated yields of 81-83% could be consistently attained. Traces of Bu3SnH in crude reaction products could be removed by stirring in CHCl3 with a catalytic amount of AIBN followed by filtration through silica gel.
