The rhodium-catalyzed water–gas shift reaction has been demonstrated to drive the reductive alkylation of several classes of activated methylene compounds at room temperature. Under catalysis by rhodium trichloride (2–3 mol %), carbon monoxide (10 bar), water (2–50 equiv), and triethylamine (2.5–7 equiv), the scope has been successfully expanded to cover a wide range of alkylating agents, including
