文摘

We report magnesium-catalyzed cross-dehydrocoupling of Si鈥揌 and N鈥揌 bonds to give Si鈥揘 bonds and H₂. A number of silazanes are accessible using this method, as well as silylamines from NH₃ and silylhydrazines from N₂H₄. Kinetic studies of the overall catalytic cycle and a stoichiometric Si鈥揘 bond-forming reaction suggest nucleophilic attack by a magnesium amide as the turnover-limiting step.
