Reactions of a N-Heterocyclic Carbene-Stabilized Bromoiminoborane with Nucleophiles: Access to the Functionalized Lewis Base-Stabilized Iminoboranes

As the isoelectronic congeners of imines, however, the structural diversity of Lewis base-stabilized iminoboranes is much lower than that of imines, which indeed prohibits their use in coordination chemistry and catalysis. In this work, the reactions of a N-heterocyclic carbene-stabilized bromoiminoborane with alkali-metal salts or grignard reagents are reported, which lead to the formation of a series of Lewis base-stabilized amino, alkoxyl, phosphino, alkyl, and alkynyl substituted iminoboranes. This study demonstrates a facile synthetic route to access functionalized Lewis base-stabilized iminoboranes.
