The tungsten benzylidyne complex [PhCWOSi(OtBu)3}3] efficiently catalyzes the metathesis of conjugated diynes and ring‐closing diyne metathesis (see scheme). Although this reaction implies CC single‐bond activation, 13C labeling studies reveal that it proceeds by classical alkylidyne group exchange and involves cleavage and formation of carbon–carbon triple bonds.
苄基钨络合物[PhCWOSi(O t Bu)3 } 3 ]有效催化共轭二炔的复分解和闭环二炔的复分解(参见方案)。虽然此反应意味着Ç C单键活化,13 Ç标记研究表明,它前进通过经典次烷基组交换并涉及切割和形成的碳-碳三键。
