A heterogeneous cobalt catalyst for C–C bond formation by a borrowing hydrogen strategy†
Abstract
A MgO-co-deposited Co catalyst could more efficiently promote the α-alkylation of ketones with alcohols via a borrowing hydrogen mechanism than a Ru-based catalyst. Controlled experiments revealed that MgO promoted the hydrogenation step and the TiO2 support contributed to the condensation step in the reaction sequence.
