Abstract

Reaction of excess Ph2SNH (1) with [PPh4](2)[Pd2Br6] results in the formation of homoleptic [Pd(Ph2SNH)(4)]Br-2. In contrast the analogous reaction of the N-substituted sulfimide Ph2SN-CH2CH2CN (2) with [PPh4](2)[Pd2Br6] only results in the formation of trans-[PdBr2(Ph2SNCH2CH2CN)(2)] (3) even if the ligand is present in large excess. Lowering the reaction ratio to 2:1 (ligand: dimer) allows isolation of [PPh4][PdBr3(Ph2SNCH2CH2CN)] (4). Compounds 3 and 4 constitute the first examples of fully characterised complexes of N-substituted sulfimides and X-ray crystallography confirm the ligands tobe bound to the metal through nitrogen; although the nitrile end groups ofthe substituents have the potential to bind to metals, no evidence for this is seen in these particular systems.
