Abstract

Ligands, (2E)-2-(1-phenylethylidene)hydrazine-1-carboxamide (L1) and (2E)-N-phenyl-2-(1-phenylethylidene)hydrazine-1-carboxamide (L2), were synthesized, as well as cyclometallic palladium(II) complexes [(PdL1)2Cl]Cl and [(PdL2)2Cl]Cl with them. Their composition and structure were proven by 1H, 13C, 1H–13C HMQC, 1H–13C HMBC, 1Н–1Н dqf–COSY and 1H–1H NOESY NMR spectroscopy, mass spectrometry, IR and electron spectroscopy. Catalytic activity of the obtained complexes in the Suzuki–Miyaura C–C cross-coupling reactions was demonstrated.
