A straightforward method for the hydrophenoxylation of internal alkynes, using N-heterocyclic carbene-based copper(i) and gold(i) complexes, is described. The heterobimetallic catalytic system proceeds via dual activation of the substrates to afford the desired vinylether derivatives. This methodology is shown to be highly efficient and tolerates a wide range of substituted phenols and alkynes.
本文描述了一种使用基于氮杂环卡宾的铜（I）和金（I）配合物对内炔进行氢酚氧基化的直接方法。这种异双金属催化体系通过底物的双重活化来提供所需的乙烯基醚衍生物。该方法被证明是高效的，并且能耐受多种取代酚和炔烃。
