Palladium hydrazonato complexes and their role in the Pd-catalyzed cross-coupling reactions of hydrazones as carbene precursors

Abstract

Hydrazones are common carbene precursors in many palladium-catalyzed cross coupling reactions of carbenes as a coupling partner, but their interaction with palladium has been overlooked. We have found that hydrazonato...

Acyl hydrazone‐based supramolecular polymer for ultrasensitive detection of Fe3+, Pd2+, H2PO4− and its application for Suzuki coupling reactions

“…In the past few years, homogeneous palladium catalytic systems exhibited excellent catalytic activity for Suzuki coupling reaction, which is one of the most efficient method for the construction of C-C bonds to provide symmetric biaryl derivatives. [27][28][29] However, the application of homogeneous palladium catalytic systems was limited by the high cost, sensitivity to air and water, difficulty in separation, and the need for toxic ligands. In the view of environment-friendly and green chemistry, the development of ligand-free heterogeneous catalysts is an effective way to address these disadvantages.…”
