摘要：

Reaction of aryltellurium tribromides with alkynes in methanol affords (E)-beta-bromovinyl aryltellurium dibromides and in benzene gives the (Z)-isomer, which can be reduced by sodium borohydride to yield (Z) or (E)-beta-bromovinyl tellurides respectively. Copyright (C) 1996 Elsevier Science Ltd
