We report on the activation of CO2 by the well-defined alkylzinc hydroxide (tBuZnOH)6 in the absence and presence of tBu2Zn as an external proton acceptor. The slight modifications in reaction systems involving organozinc precursors enable control of the reaction products with high selectivity leading to the isolation of the mesoporous solid based on ZnCO3 nanoparticles or an unprecedented discrete alkylzinc carbonate [(tBuZn)2(μ5-CO3)]6 cluster with the Zn-C bond intact, respectively.
我们报告了在无和有叔丁基锌(tBu2Zn)作为外部质子受体的情况下,由定义明确的烷基锌氢氧化物(tBuZnOH)6 激活 CO2 的情况。通过对涉及有机锌前体的反应体系进行轻微的修改,可以控制反应产物的高选择性,从而分别分离出基于 ZnCO3 纳米粒子的介孔固体或具有完整 Zn-C 键的前所未有的离散烷基锌碳酸盐[(tBuZn)2(μ5-CO3)]6 簇。
