Abstract
A highly stereoselective alkyne semihydrogenation with copper(I) complexes is reported. Copper-N-heterocyclic carbene complex catalysts, bearing an intramolecular Cu-O bond, allow for the direct transfer of both hydrogen atoms from dihydrogen to the alkyne. The corresponding alkenes can be isolated with high Z selectivity and negligible overreduction to the alkane.
摘要
据报道，铜（I）配合物可实现高度立体选择性的炔烃半氢化反应。带有分子内Cu-O键的铜-氮杂环卡宾配合物催化剂能够使两个氢原子从氢气直接转移至炔烃上。相应的烯烃能够以高Z选择性分离出来，且过度还原为烷烃的程度可忽略不计。
