Abstract

Irradiation of o-formylbenzyltrialkylstannanes in benzene gives α-trialkylstannoxy-o-quinodimethanes which are trapped with dienophiles at room temperature to afford cycloadducts with high stereoselectivities, while the corresponding silane and germane gave a different type of o-quinodimethane and moderate stereoselectivities in cycloadditions.
