摘要

试图合成一种双硫代钨烷基烯催化剂，该催化剂在二甲醚的活化下意外生成了体积庞大的烯硫代酸酯(通式[W(NAr)(CHCMe3)(SAr ')(κ 2 -O-CH2 -CH2 -OMe)]的五配位配合物，与母体双苯硫代酸酯相比，它对顺式-4-壬烯的自分解具有活性)。

Synthesis and Reactivity of a Pentacoordinated Thiolate-Based Imido-Alkylidene W(VI) Complexes

Attempt to synthesize a bis-thiolate tungsten alkylidene catalysts with bulky arenethiolates unexpectedly yielded upon activation of DME a pentacoordinated complex of general formula [W(NAr)(CHCMe3 )(SAr’)(κ 2 -O-CH2 -CH2 -OMe)], which is active towards self-metathesis of cis-4-nonene compared to the parent bis-benzenethiolate.
