  摘要：

  AbstractReaction of [PPh4]2[Pd2X6] (where X = Cl, Br or I) with 1,4‐(PhS{NH})2C6H4 (1) in dichloromethane results in the formation of [Pd{1,4‐(PhS{NH})2C6H4}X2]2 (2). X‐ray crystallography (performed using a synchrotron source) confirms that in the case where X = Br (2a) both the bis‐sulfimides act as bridging ligands through N−Pd bonds producing an 18‐membered ring system linking the four sulfur atoms into an almost perfect square. Changing the reaction solvent to methanol/dichloromethane results in the formation of a polymeric material. Reaction of [PdCl2(PhCN)2] with 1,2‐(PhS{NH})(PhS)C6H4 (3) results in the formation of [PdCl2{1,2‐(PhS{NH})(PhS)C6H4}] (4) in which 3 acts as a bidentate ligand, bound by N−Pd and S−Pd bonds to form a unique MSCCSN metallacycle. The Pd−S bond is broken upon reaction with one equivalent of PPh3, generating trans‐[PdCl2{1,2‐(PhS{NH})(PhS)C6H4}PPh3] (5); further reaction with PPh3 results in complete removal of 3 from the system and formation of trans‐[PdCl2(PPh3)2].
