Unexpected mild C–N bond cleavage mediated by guanidine coordination to a niobium iminocarbamoyl complex

Abstract

The complex [Nb(NMe2)2{(NMe2)C[double bond, length as m-dash]NtBu}{N(2,6-iPr2C6H3)}] reacts with trialkylguanidines and undergoes a room temperature C–N bond cleavage of the iminocarbamoyl moiety. This reaction affords the guanidinate complexes [Nb(NMe2)2{N(2,6-iPr2C6H3)}{(NiPr)2C(NHiPr)}] or [Nb(NMe2)2{N(2,6-iPr2C6H3)}{(NiPr)2C(NHnBu)}] and free isocyanide. The first crystal structure of a niobium iminocarbamoyl complex is reported.
