Aminolysis of bis[bis(trimethylsilyl)amido]-manganese, -iron, and -cobalt for the synthesis of mono- and bis-silylene complexes

We report a method for the synthesis of amidinate stabilized silylene (NHSi) metal-halide complexes from M{N(SiMe 3 ) 2 } 2 (M = Mn, Fe, Co). The reported reactions can be used to make mono-silylene or bis-silylene complexes and the resulting products can be easily controlled by the reaction stoichi...

Description
Summary:We report a method for the synthesis of amidinate stabilized silylene (NHSi) metal-halide complexes from M{N(SiMe 3 ) 2 } 2 (M = Mn, Fe, Co). The reported reactions can be used to make mono-silylene or bis-silylene complexes and the resulting products can be easily controlled by the reaction stoichiometry. Additionally, we apply this new synthetic protocol for the synthesis of a bis-iron complex derived from a bis-amidinate ligand having a terphenyl backbone. Mono- and bis-silylene metal complexes may be synthesized in high yield from M{N(SiMe 3 ) 2 } 2 and PhC(N t Bu) 2 SiHCl 2 .
