摘要：

Oxidative addition of diaryl disulphides RSSR to low-valent transition metal carbonyl Re(2)(CO)(10) with monodendate pyridine ligands bring forth novel sulphur bridged neutral dinuclear rhenium metallacycles [L(CO)(3)Re(mu-SR)(2)Re(CO)(3)L] (1-9) (L = pyridine ligand, R = aryl group) under one pot reaction conditions. The Metallacycles 1-9 have been characterised by elemental analysis, NMR and IR and absorption spectral analysis. Molecular structures of 4, 8 and 9 were determined by crystallographic analysis and the structural studies reveal that pyridyl groups attached to metal centres exhibit cis conformation.
