Abstract

Through the reaction of the aminotroponiminatogermylene monochloride complex [(Bui2ATI)GeCl] (1) with sodium pyrrolide, the stable N-germylene pyrrole complex [(Bui2ATI)GeNC4H4] (2) has been isolated. The reaction of compound 2 with thiophenol and selenophenol afforded the first germylene thio- and selenophenoxide complexes [(Bui2ATI)GeSPh] (3) and [(Bui2ATI)GeSePh] (4) through the substitution of the pyrrole moiety (NC4H4) with an EPh moiety (E = S (3), Se (4)), respectively. Interestingly, the chalcogenide derivatives of compound 2, such as the N-germathioacylpyrrole complex [(Bui2ATI)Ge(S)NC4H4] (5) and N-germaselenoacylpyrrole complex [(Bui2ATI)Ge(Se)NC4H4] (6), also underwent the aforementioned substitution reaction with thiophenol and selenophenol, resulting in the first examples of germa thioester complexes ([(Bui2ATI)Ge(S)SPh] (7) and [(Bui2ATI)Ge(Se)SPh] (8)) and germa selenoester complexes ([(Bui2ATI)Ge(S)SePh] (9) and [(Bui2ATI)Ge(Se)SePh] (10)), respectively. All the novel germanium compounds ...
