Abstract

The utility of W-alkylidene complexes for enyne ring-closing metathesis is demonstrated in a direct comparison with Mo-based analogs. Tungsten complexes lead to less alkyne oligomerization and higher levels of endo-selectivity and enantioselectivity.

摘要

W-亚烷基配合物在烯炔环 closing metathesis 中的应用通过与 Mo 基类似物的直接比较得到了证明。钨配合物导致较少的炔烃低聚和更高水平的endo-选择性和对映选择性。
