hydrostannylation reactions involving electron-rich olefins results in a dramatic improvement in yield. For example, reaction of α-[(tert-butyl)dimethylsilyl]oxy}styrene (1) with triphenylstannane (2a; 1.1 equiv.) in the presence of PhSeSePh and 2,2′-azobis[2-methylpropanenitrile] (AIBN) affords 2-[(tert-butyl)dimethylsilyl]oxy}-2-phenylethyl}triphenylstannane (3a) in 95% yield after 2 h. This reaction presumably
