The chameleon reductant : CO 2 trapped by a frustrated Lewis pair is predicted to undergo BH activation mediated reduction by NH 3 BH 3 , in contrast to concerted NH 3 BH 3 reduction of free CO 2 (see figure). This mechanism provides further fundamental understanding of novel CO 2 reduction processes that could lead to environmentally friendly and economically viable production of renewable fuels.
