摘要

Abstract In sharp contrast to the expected formation of a telluride-palladium complex, the treatment of either (E, E)-and (Z, Z)-distyryl tellurides (1 and 2) or (E)-and (Z)-styryl phenyl tellurides (5 and 6) with Li 2 PdCl 4 in acetonitrile at 25 C results in the formation of stereoisomeric 1, 4-diphenylbuta-1, 3-dienes, whereas the treatment of 1 and 2 with Pd (OAc) 2 produces styryl acetates solely or mainly.
