 It deprotonates the free amine to yield the magnesium bis(trimethylsilyl)amide, itself commercially available.In contrast to group 1 metals, the amine N-H in bis(trimethylsilyl)amine is not acidic enough to react with the group 2 metals, however complexes may be prepared via a reaction of tin(II) bis(trimethylsilyl)amide with the appropriate metal
