Abstract

Nickel catalysed Suzuki reactions of phenyl boronic acids with aryl diazonium salts in glycerol as a reaction medium are reported. Various aryl diazonium salts were efficiently reacted with aryl boronic acids under optimized conditions to give the respective diaryl compounds in good to excellent yields. The base free conditions and use of glycerol as a solvent, which can be recycled successfully for up to five consecutive cycles, make the present protocol environmentally benign in nature.
