dc.description.abstractThe reaction of S-(Ph2P)(2)N(CHMePh) with sulfur (1:1 molar ratio) in diethyl ether solution leads to S-Ph2P(S)N(CHMePh)PPh2 (1). The disulphide S-{Ph2P(S)}(2)N(CHMePh) (2), was obtained when the reaction was carried out in tetrahydrofuran with an excess of sulfur (1:5 molar ratio). 1 reacts with the solvated rhodium. (I) complex [Rh(cod)S-x]BF4 to afford the cationic complex [Rh(cod){eta(2)-S,P-Ph2P(S)N(CHMePh)PPh2}]BF4 (3). However, when the above reaction was carried out with 2, cleavage of the C-N bond of the ligand occurred, to yield the complex [Ph(cod)(eta(2)-S,S-{Ph2P(S)}(2)NH)]BF4 (4). Reactions of I with the fragments of Rh (III) and Ir (III) [Cp*MClSx]BF4 lead to cleavage of the C-N bond of the ligand yielding cationic complexes, [(Cp*)MCl{eta(2)- P,S-Ph2PNHP(S)Ph-2}]BF4 (M = Rh, 5; Ir, 6]. Crystal structures of 1, 2, 5 and 6 have beet determined by X-ray diffraction methods. Compounds 1 and 1 crystallize in the same space group P2(1)2(1)2(1). The molecular structure of 1 shows a nearly trigonal planar nitrogen atom bound to two different phosphorus atoms and to the chiral carbon atom. Compound 2 acquires a twisted conformation with the two sulfur atoms adopting mutually trans positions with respect to the PNP backbone. (C) 2002 Elsevier Science B.V. All rights reserved.
