A photoredox activation mode of formate salts for carboxylation was developed. Using a formate salt as the reductant, carbonyl source, and hydrogen atom transfer reagent, a wide range of alkenes can be converted into acid products via a carboxyl group tra

A carbene insertion into electron-deficient C?H bonds of 1,3-diesters, β-ketoesters, β-ketonitriles, and malononitriles was realized by using CuCN/PCy3 as the catalyst. The reaction provides a straightforward approach to the synthetically important multi-substituted succinic acid derivatives. A plausible reaction mechanism with cyclopropanation/ring opening as key steps was proposed based on control experiments.
Stereoselective One-Pot Synthesis of cis-1,2-Dicyanoalkenes from 1,1-Bis(benzenesulfonyl)alkenes and KCN

An efficient synthesis of cis-1,2-dicyanoalkenes by the reaction of 1,1-bis(benzenesulfonyl)alkenes with KCN was developed. This reaction was conducted in the presence of tetrabutylammonium bromide and NH4Cl/K3PO4 under phase-transfer conditions. A series of cis-1,2-dicyanoalkenes were obtained in good to high yields. Further transformation of the obtained product allows for access to imide and dicarboxylic acid compounds.
