efficient approach was developed for the α-alkylation of various nitriles with carbonyl compounds using ruthenium-amido complex catalyst 1. The C-C bond was formed through aldol reaction followed by hydrogenation with triethylamine-formic acid (TEAF) and 1. Moderate to high yields were obtained, and a variety of functional groups were tolerated, including nitro and chloro groups, and a furan ring. ruthenium-amido

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
