1Salt metathesis versus protonolysis routes for the synthesis of silylamide Hauser base (R2NMgX; X = halogen) and amido-Grignard (R2NMgR) complexes.

Goodwin CA1, Smith A, Ortu F, Vitorica-Yrezabal IJ, Mills DP.

Dalton Trans. 2016 Apr 14;45(14):6004-14. doi: 10.1039/c5dt02535d. Epub 2015 Aug 14.

The preparation of silylamide Hauser base (R2NMgX; X = halide) and amido-Grignard (R2NMgR) complexes from simple Grignard reagents using [K{N(SiMe2(t)Bu)2}]n, [K{N(SiMe2(t)Bu)(Si(i)Pr3)}]n and [K{N(Si(i)Pr3)2}]n, and their parent silylamines, was explored. Both salt metathesis and protonolysis routes proved ineffective with allylmagnesium chloride as a starting material due to complex Schlenk equilibria, with [Mg(N(RR'))(μ-Cl)(THF)]2 (N(RR') = {N(Si(t)BuMe2)2}(-), 1; {N(Si(t)BuMe2)(Si(i)Pr3)}(-), 2; {N(Si(i)Pr3)2}(-), 3) and [Mg{N(Si(i)Pr3)2}(μ-C3H5)]∞ (4) identified as minor products.
