Abstract

In the presence of B(C₆F₅)₃ five-membered heteroarenes undergo dehydrosilylation and hydrosilylation with silanes. The former, favoured on addition of a weak base, produces H₂ as a by-product making the process catalytic in B(C₆F₅)₃ but also enabling competitive heteroarene hydrogenation.
