The dehydropolymerization of H3B•NMeH2 to form polyaminoboranes using [Rh(Xantphos–alkyl)] catalysts

Abstract:

A systematic study of catalyst structure and charge for the dehydropolymerization of H3B•NMeH2 to form N-methylpolyaminoborane is reported using catalysts based upon neutral and cationic {Rh(Xantphos-R}} fragments, in which PR2 groups are selected from Et, iPr and tBu. The most efficient systems are based upon {Rh(Xantphos-iPr}}, i.e. [Rh(3–P,O,P–Xantphos–iPr)(H)2(2–H3B•NMe3)][BArF4], 6, and Rh(3–P,O,P–Xantphos–iPr)H, 11. While H2 evolution kinetics show both are fast catalysts (ToF ~ 1500...
