Herein we report the synthesis of a family of copper(I) diphosphine bifluoride complexes, their characterization, and their use as efficient preactivated catalysts for nucleophilic copper addition of pronucleophiles on unsaturations. Their use as mechanistic probes is also highlighted by the identification of two copper deuterides.

铜（I）二膦铜氟化物络合物作为不饱和官能团上亲核加成的高效预活化催化剂

本文中，我们报道了铜（I）二氟化氢二膦铜配合物家族的合成，其表征以及它们在不饱和基团上亲核体亲核铜加成的有效预活化催化剂中的用途。通过鉴定两种铜氘化物也突出了它们作为机械探针的用途。
