Abstract
Treatment of the ruthenium complex [Ru]-C=C(Ph)C(=S)N(Ph)C(=NPh)S (3, [Ru] = Cp(dppe)Ru) containing a heterocyclic [1,3]-thiazine-4-thione six-membered-ring ligand with various organic halides results in alkylation at the thione sulfur terminus of the ligand to yield [Ru]-C=C(Ph)C(SCH 2R)N(Ph)C(=NPh)S][X] (4a, R = CN, X = I; 4b, R = Ph, X = Br; 4c, R = CH = CH 2, X = I, 4d, R = p-C 6H 4CF 3, X = Br). Similarly the reaction of 3 with HgCl 2 at room temperature affords [Ru]-C=C(Ph)C(SHgCl)N(Ph)C(=NPh)S][Cl] (5). Transformation of 5 to the cationic vinylidene complex [Ru]=C= C(Ph)C(O)NHPh 2[Hg 2Cl 6] (6) readily occurred in the air. The structures of 4c and 6 are determined by single crystal X-ray diffraction analysis. © 2002 Published by Elsevier Science B.V.
