Abstract

An in situ catalytic system was generated based on hydrazone-thioether ligands and Pd(OAc)2. It provided excellent catalytic activity in the Suzuki-Miyaura cross-coupling reactions between aryl halides and arylboronic acids in aqueous medium and under IR irradiation. The resulting coupled products were obtained in short reaction times, with low catalyst loads and in good to excellent yields. Density functional theory based computations were applied to characterize the probable structure of the dimeric complex formed between the hydrazone and Pd(OAc)2, afterwards structure was confirmed by experimental analysis of IR and ESI mass spectrometry.
