研究了双金属对化学计量比β-氢化物消除和迁移插入反应的影响。双金属反应条件驱动Cu处的β-氢化物消除，而在不存在β-氢的情况下发生β-C-B消除。炔在Ni上的固有迁移插入化学在C-H反应条件下转向有利于C-H去质子化。
Bimetallic effects on stoichiometric β-hydride elimination and migratory insertion reactions were examined. Bimetallic reaction conditions drove β-hydride elimination at Cu, while bimetallic C-B elimination occurred in the absence of β-hydrogens. The inherent migratory insertion chemistry of alkynes at Ni was diverted under bimetallic reaction conditions to favor C-H deprotonation.
