Treatment of the imine PhC(=NSiMe3)py with Et2BOMe or BF3•Et2O afforded bicyclic ketiminoboranes 4a and 4b via intramolecular N-coordination. The basicity of the imine N is evidenced by their reactivity towards Brønsted and Lewis acids and the structures of 4a•HCl and 4b•BF3 are reported as well as the dipyridyl imine derivative 4c•HCl.
