Methylseleno-derivatives of Group IV

Abstract

The synthesis of a series of methylseleno-derivatives of Group IV, Me_{4 –n}M(SeMe)_n(M = Si, Ge, or Sn, n= 1–4), is reported. The preparative routes include reactions of methaneselenol with Group IV amines; the dehydrohalogenation of methaneselenol and a Group IV halide; and the reactions of Group IV halides with ‘methylselenolithium’, methylselenomagnesium iodide, lithium tetramethylselenoaluminate, and methylseleno(trimethyl)silane. The n.m.r. and vibrational spectra are reported and discussed. The reactions of the series Me₃MSeMe with some protic reagents were studied.
