Abstract

[Mg(Form)2(THF)] [Form = bis(2,6-dimethylphenyl)formamidinate (XylForm) (1), bis(2,6-diethylphenyl)formamidinate, (EtForm) (2), bis(2,6-diisopropylphenyl)formamidinate (DippForm) (3)] are conveniently synthesized by treating bis(2,6-dimethylphenyl)formamidine, bis(2,6-diethylphenyl)formamidine, or bis(2,6-diisopropylphenyl)formamidine, respectively, with half an equivalent of dibutylmagnesium in THF. Compounds 1–3 are mononuclear species in the solid state with five coordinate central metal atoms. The 1H NMR chemical shift of the formamidinate formyl proton exhibits a correlation with ligand sterics wherein increasing bulk leads to a shift to higher field.
