Abstract :
Hydrostannations of primary propargylic alcohols with Bu3SnH catalyzed by Pd(PPh3)2 yield (E) allylic alcohols in which the Bu3Sn group is affixed to the carbon proximal to the CH2OH substituent, suggestive of an OH directing effect. Hydrostannations of the related propargylic acetates show no such effect.
