Easy as A, B[BOND]C: B[BOND]C cross-coupling on [3,3′-Co(8-I-1,2-C2B9H10)(1′,2′-C2B9H11)], [1], the best specimen of metallacarboranes, is easily produced in a reaction mediated by Li+ in the absence of a transition-metal catalyst (see figure). Pure RLi or a mixture of Li reagents (tBuLi+RLi) is adequate to produce the B[BOND]C bond. Notably, a threshold of RLi (or tBuLi+RLi)/[1], 2:1, is required to initiate the B[BOND]C coupling, which acts, at least in part, as a source of soluble Li+.
