摘要

用两种等价物[K(C5Me5)]处理[ThCl4(DME)2]时，外来水的存在导致标题桥接氧配合物[{(C5Me5)2ThCl}2(μ-O)]的形成(1)。这种配合物也可以由[(C5Me5)2ThCl2]与一等量的脱气水反应形成。用Me3SiCl和AlCl3探测氧配合物的反应性，定量生成[(C5Me5)2ThCl2]。用两种等效的MeMgCl处理[{(C5Me5)2ThCl}2(μ-O)]得到[{(C5Me5)2ThMe}2(μ-O)](2)，再用PhN(H)N(H)Ph处理，得到[{(C5Me5)2Th(PhNN(H)Ph)}2(μ-O)](3)。每个配合物都用光谱和结构方法进行了表征。

Reactivity of a dithorium oxo complex from adventitious water†

The presence of adventitious water in the treatment of [ThCl₄(DME)₂] with two equivalents of [K(C₅Me₅)] results in the formation of the title bridging oxo complex, [{(C₅Me₅)₂ThCl}₂(μ-O)] (1). This complex can also be formed from the reaction of [(C₅Me₅)₂ThCl₂] with one equivalent of degassed water. The reactivity of the oxo complex was probed with Me₃SiCl and AlCl₃, resulting in the quantitative formation of [(C₅Me₅)₂ThCl₂]. Treatment of [{(C₅Me₅)₂ThCl}₂(μ-O)] with two equivalents of MeMgCl leads to [{(C₅Me₅)₂ThMe}₂(μ-O)] (2) which can be further treated with PhN(H)N(H)Ph, yielding [{(C₅Me₅)₂Th(PhNN(H)Ph)}₂(μ-O)] (3). Each complex has been characterized by spectroscopic and structural methods.
