Neutral molecular zinc(ii) dihydrides supported by N-heterocyclic carbene ligands bearing a pendant phosphine group were synthesized and then reacted with carbon dioxide to afford zinc diformates. The zinc dihydrides were found to be active catalysts for hydroboration of carbon dioxide under mild conditions, selectively giving boryl formate, bis(boryl)acetal, or methoxy borane compounds by changing the nature of the borane reductant.
合成了由带有侧链膦基团的N-杂环卡宾配体支撑的中性分子二氢锌（II），然后使其与二氧化碳反应生成二甲酸锌。发现二氢锌在温和条件下是二氧化碳硼氢化反应的活性催化剂，通过改变硼烷还原剂的性质可选择性地生成硼酸甲酸酯、双（硼酸酯）缩醛或甲氧基硼烷化合物。
