Characterization of Monohalogen and Monopseudohalogen Derivatives of Dimethylgermane

Abstract

The high yield syntheses of Me2GeHX (X = F, Cl, Br, I) and Me2GeHPs (Ps = CN, N3, NCO, NCS, OAc) are reported. The dimethylgermane derivatives are identified and characterized by various physical methods and by cleavage reactions where appropriate. A normal coordinate analysis based on a modified valence force field provides confirmation of the assignments for all the fundamental frequencies, except the torsional modes, in the vibrational spectra of the monohalogeno(dimethyl)germanes, Me2GeHX.
