Abstract

¹³C NMR spectroscopy has been used to determined the barriers to rotation about the BN bonds of 1-(N-benzyl-N-methylamino)borepin and 1-(N-benzyl-N-methylamino)-4,5-dihydroborepin as 18 and 19.8 kcal mol^-1, respectively. The corresponding rotational barriers of a variety of aminoboranes have been calculated using the semi-empirical AM1 method.
