Abstract

A reaction of [PdCl2(cod)] (cod = 1,5-cyclooctadiene) and an E/Z mixture of quinoline-2-carbaldehyde (pyridine-2-carbonyl)hydrazone (HL) gave two kinds of PdII mononuclear complexes, [PdCl(Z-L-κ3N,N′,N″)] (1) and [PdCl2(E-HL′-κ2N,N′)] (2), where L- is the deprotonated hydrazonate anion and HL′ is the quinolinium-hydrazonate zwitterionic form of HL. Complex 2 is gradually converted to 1 in solution, and complex 1 is a good precursor to prepare a PdII/RuII heterodinuclear complex bridged by hydrazonate, trans(Cl,Cl)-[RuCl2(PPh3)2(μ-L)PdCl] (3).
