Palladacycles with C,N-bidentate and N,C,N′-tridentate ligands: Structures, spectral study and catalytic methanolysis of P S pesticides

A study of the reactivity of [Pd({(η5‐C5H3)–CH=N–(CH2)n–(C4H3S)}Fe{η5‐C5H5})Cl], n = 2 (1e) or 1 (1f), with symmetric alkynes R1–C≡C–R1 (R1 = CO2Me, Et or Ph) has allowed us to achieve the di‐μ‐chloro‐bridged complexes [Pd({(MeO2C–C=C–CO2Me)(η5‐C5H3)–CH=N–(CH2)n–(C4H3S)}Fe{η5‐C5H5})μ‐Cl]2, n = 2 (3e) or 1 (3f), and the mononuclear derivatives [Pd({(MeO2C–C=C–CO2Me)(η5‐C5H3)–CH=N–(CH2)n–(C4H3S)}Fe{η5‐C5H5})Cl(PPh3)], n = 2 (4e) or 1 (4f), [Pd({(R1–C=C–R1)2(η5‐C5H3)–CH=N–(CH2)n–(C4H3S)}Fe{η5‐C5H5})Cl],R1 = CO2Me, n = 2 (5e) or 1 (5f), R1 = Et, n = 2 (6e) or 1 (6f), or R1 = Ph, n = 2 (7e), and [Pd({(Ph–C=C–Ph)2(η5‐C5H3)–CH=N–(CH2)–(C4H3S)}Fe{η5‐C5H5})Cl(PPh3)] (7f·1/2Ph–C≡C–Ph). With MeO2C–C≡C–CO2Me, mono‐ (3e, 3f, 4e and 4f) and bis‐insertion complexes (5e and 5f) were obtained, whereas for R1–C≡C–R1 with R1 = Et or Ph, only bis‐insertion products (6e, 6f, 7e and 7f) were isolated. These studies also proved that 1e and 1f, which have a labile Pd–S(thienyl) bond, are more prone to undergo the insertion of R1–C≡C–R1 (R1 = CO2Me, Et or Ph) than their analogues with [C(sp2, ferrocene), N, X]– [X = O, N(amine) or S(thioether)] pincer ligands.
