Desulfuration reactions of germadithiolanes by trialkylphosphines lead to germathiones via intermediate germathietanes. The formation of germylenes finally observed arises from reduction of germathiones by trialkylphosphines. Analogous reduction reactions of germanones by three coordinated linear and cyclic phosphorus compounds are also described.

Delithiochloration of N-lithio-N-dimesitylchlorogermyl-3-amino-2-methyl-thiophoate at low temperature leads to the corresponding germa-imine, stabilized by the steric effects of mesityl substituents linked to germanium and possibly by mesomeric effects with the thiophoate group. This germa-imine, stable at room temperature was characterized by spectrometry (IR, UV, RMN, DCi mass spectrometry). With specific reagents (MeOH, Et3NH+Cl-, etc.) the reactivity is different from that of cyclodiger-mazanes, dimers of germa-imines; stoichiometric addition of MeOH and HCl without cleavage of germanium-nitrogen bond is observed. 3,5-Di-t-butylorthoquinone leads to the expected germadiox-olane, through decomposition of the transient 1,4-cycloadduct observed in H-1 NMR.
