The adduct [MeO ¿ Bpin-Bpin]- efficiently mediates the ¿-boration of ¿,¿-unsaturated imines formed in situ. The use of chiral phosphines as additives, and in particular the chiral phosphine (S)-MeBoPhoz, enables the catalytic asymmetric reaction to proceed with higher enantioselectivity than the analogue copper(i) mediated reaction.
