摘要

The palladium-catalyzed cross-coupling reaction (Stille coupling) of aromatic iodides Ar I and tributyl (ethynyl) tin Bu3SnC CH form the aromatic acetylides Ar C CH and the side product tributyltin iodide Bu3SnI in equimolar amount. In situ addition of lithium diisopropylamide (LDA) to this crude mixture directly affords the tributyl (ethynyl) tin aromatics Ar C C SnBu3 in high yield. In the case of the bis (iodoaromatic) I Ar I ( ...
