Abstract

The thorium benzyne complex (η-CH)ThCl was synthesized in the gas phase through consecutive decarboxylation and dehydrochlorination from the (CHCO)ThCl precursor upon collision-induced dissociation. Theoretical calculations suggest that (η-CH)ThCl exhibits a metallacyclopropene structure with two polarized Th-C σ bonds. This procedure can be generally extended to the synthesis of a wide range of gas-phase thorium benzyne complexes.

摘要

通过碰撞诱导解离，使（CHCO）ThCl前体连续脱羧和脱氯化氢，在气相中合成了钍苯炔配合物（η-CH）ThCl。理论计算表明，（η-CH）ThCl具有含两个极化Th-C σ键的金属环丙烯结构。该方法通常可扩展用于合成多种气相钍苯炔配合物。
