Mechanisms of the Reactions of B-Substituted Amine Boranes with THF·BH3

The reactions of NH3BH2R (R = Me, Ph and Cl) with THFBH3 have been investigated and it was found that different substituents on the B atom help to proceed the reactions in different ways. The expected doubly-bridged B-substituted aminodiborane products, similar to aminodiborane (ADB, BH2(μ-H)(μ-NH2)BH2) via the reaction of ammonia borane (AB, NH3BH3) and tetrahydrofuran borane (THFBH3), are not obtained. Two competitive reactions occurred with the change of R = Me or Ph. When R is a Me group, an “open“ version of B-substituted μ-aminodiborane, THFBH(Me)(μ-NH2)BH3, is formed as a major product; when R is a Ph group, AB and THFBH2Ph are formed as main products via the intermolecular NH3–THF exchange reaction. However, if R is Cl, then NH3BH2Cl reacts with THFBH3 through reversible intermolecular Cl–H exchange mechanism. Furthermore, DFT calculations are performed to elucidate the formation mechanism of THFBH(Me)(μ-NH2)BH3 via the reaction of NH3BH2Me and THFBH3 as well as the exchange mechanism of Cl–H in the reaction of NH3BH2Cl and THFBH3.
