The magnesium hydride and methyl compounds, [TismPriBenz]MgX (X = H, Me), react with diphenylamine (Ph2NH)and pyrrolidine (C4H8NH)to afford the amide derivatives, [TismPriBenz]MgNPh2 and [TismPriBenz]MgNC4H8, while reactions with the terminal alkynes, PhC[tbnd]CH and BunC[tbnd]CH, afford the corresponding acetylide derivatives, [TismPriBenz]MgC[tbnd]CPh and [TismPriBenz]MgC[tbnd]CBun. The Mg[sbnd]N bond of [TismPriBenz]MgNR2 may be cleaved by hydrosilanes, such that [TismPriBenz]MgMe is an effective precatalyst for the dehydrocoupling of hydrosilanes and amines. For example, [TismPriBenz]MgMe enables the conversion of a 1:1 mixture of Ph2SiH2 and C4H8NH at room temperature to the silazane, Ph2SiH(NC4H8). [TismPriBenz]MgH and [TismPriBenz]MgMe are also capable of dehydrocoupling PhC[tbnd]CH and PhSiH3 to form PhSiH2C[tbnd]CPh. In addition to dehydrocoupling of terminal alkynes, [TismPriBenz]MgMe is also capable of achieving the isomerization 3-phenyl-1-propyne to phenylallene.

We report magnesium-catalyzed cross-dehydrocoupling of Si-H and N-H bonds to give Si-N 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-N bond-forming reaction suggest nucleophilic attack by a magnesium amide as the turnover-limiting step.
