The remarkably distinct reactivity of hydridozinc heterobimetallic cubanes [(HZnOtBu)4-n(thf LiOtBu)n] 1a-1d towards CO2 is reported--the hydride transfer from Zn-H to CO2 is drastically accelerated in the presence of Li ions in 1b-1d which led to the respective metal formate hydrates; the systems are inspiring models for the selective conversion of water gas into formates on lithium-promoted ZnO supports.
报道了氢化锌异双金属立方烷[(HZnOtBu)4-n(thf LiOtBu)n] 1a - 1d对二氧化碳具有显著不同的反应活性——在1b - 1d中锂离子的存在下，从Zn - H到二氧化碳的氢化物转移急剧加速，从而生成相应的金属甲酸盐水合物；这些体系是锂促进的氧化锌载体上合成气选择性转化为甲酸盐的启发式模型。
