Azomethine derivatives. Part XVII. Some new methyleneamino-derivatives of silicon, germanium, and tin

Abstract

The new hydrolytically sensitive yellow methyleneamino-derivatives M(N:CPh₂)₄(M = Ge or Sn), Ge (N:CR₂)₄, SiMe(N:CR₂)₃, and SiMe₂(N:CR₂)₂(R =p-toly) and GeBr₃(N:CBU^t₂)₂, GeX₂(N:CBU^t₂)₂(X = Cl or Br), and GeCl(N:CBU^t₂)₃ have been prepared from Group 4 halides and methyleneaminolithium derivatives. Features of their i.r., ¹H n.m.r., and mass spectra, and of the structures of the compounds M(N:CPh₂)₄, are reported and discussed.
