N-Methyl-anilinoborane exists as a dimer in the solid state, shown by X-ray structural analysis, whereas in solution, a monomer-dimer equilibrium is present (1H, 11B and 13C NMR spectroscopy). The phenyl groups are in trans positions in the crystalline dimer. In solution, both possible isomers of the dimer exist in a trans/cis ratio of 3:2, in agreement with the energies for calculated optimized geometries [B3LYP/6-311+G(d,p) level of theory]. In solution, the monomer is rather reactive and disproportionates completely after several days to give a 1:1 mixture of bis(N-methyl-anilino)borane and μ-(N-methyl-anilino)diborane(6). This observation led to a convenient high yield synthesis of μ-(amino)diborane(6) derivatives, starting from bis(amino)boranes and borane/THF. Copyright
