Pincer complexes of the types [Pd{C,N,N′-Ar{C(Me)=NOCH 2py-2}-2}X] or [Pd{C,N,S-C6H4{C(Me)=NOCH 2SMe}-2}Cl] (Ar = C6H4, C6H(OMe) 3-4,5,6; py-2 = 2-pyridyl; X = Cl, Br) have been prepared by reacting cyclopalladated oxime complexes [Pd{C,N-Ar{C(Me)=NOH}-2}(μ-Cl)]2 with XCH2py-2 or ClCH2SMe, respectively, in the presence of KtBuO. Various neutral and cationic derivatives have been synthesized as well as iminobenzoyl complexes resulting from the insertion of isocyanide into their Pd-Caryl bond. The cycloaddition of MeO 2CC≡CCO2Me to the oximato complex [Pd{C,N-C 6H4{C(Me)=NO}-2}(tBubpy)] (tBubpy = 4,4′-di-tert-butyl-2,2′-bipyridine) in the presence of various neutral L ligands produces pincer complexes [Pd{C,N,C′-C6H 4{C(Me)=NOC(CO2Me)=C(CO2Me)}-2}L]. Complexes of each one of the new types have been characterized by X-ray diffraction methods.
