A novel nonanuclear copper(II) complex obtained by a facile one-pot self-assembly was found to catalyze the hydroboration of ketones and aldehydes with the absence of an activator under mild, solvent-free conditions. The catalyst is air- and moisture-stable, displaying high efficiency (1980 h turnover frequency, TOF) and chemoselectivity on aldehydes over ketones and ketones over imines. This represents a rare example of divalent copper catalyst for the hydroboration of carbonyls.
通过简便的一锅法自组装得到的一种新型九核铜（II）配合物，发现在温和、无溶剂条件下，无需活化剂就能催化酮和醛的硼氢化反应。该催化剂对空气和湿气稳定，对醛相对于酮以及酮相对于亚胺表现出高效率（1980 h 周转频率，TOF）和化学选择性。这是二价铜催化剂用于羰基硼氢化反应的一个罕见例子。
