A model study on carbonylative dimerization of butyl acrylate was described here. With [RhCp*Cl2]2 as the catalyst and Ac-Gly-OH as the acidic additive, dibutyl (E)-4-oxohept-2-enedioate (2) and dibutyl 4-oxoheptanedioate (3) were synthesized.

An efficient one pot synthesis of γ-keto diesters through double Michael addition coupled with Nef reaction in the presence of CuCN catalyst and Cs2CO3 base is described. The reaction proceeds rapidly in DCM to give the products in good yields. A plausible mechanism is proposed.
