Channeling the frustration : Frustrated Lewis pairs (FLPs) consisting of Ar F 2 BH 1 with NEt 3 or DABCO can activate H 2 under mild conditions. Theoretical calculations suggest two distinct reaction pathways for these two FLPs. For the “more frustrated” Ar F 2 BH/NEt 3 , H 2 is activated in a stepwise manner; for the “less frustrated” Ar F 2 BH/DABCO, H 2 is activated in a concerted fashion (see scheme).
