air-stable, phosphine-free 8-aminoqunoline (8-AQ) based Mn(I) carbonyl complex as the catalyst for the C(α)-alkylation of oxindoles with alcohols has been developed. The Mn complex [(8-AQ)Mn(CO)3Br] works effectively as a catalyst for α-alkylation of oxindoles by both secondary as well as primary alcohols. Few pharmaceutically relevant compounds were also synthesized by this method in good yields.
