Half-sandwich ruthenium thiocarbonate complexes: Structures of CpRu(PPh3)(2)SCO2Bun, CpRu(dppe)SCO2Bun and CpRu(PPh3)(CO)SCO2Bun

摘要

Thiocarbonate ruthenium complexes of the form CpRu(L)(L')SCO2R (L = L'= PPh3 (1), 1/2dppe (2), L = PPh3, L'= CO (3); R = Et (a), Bu" (b), C6H5 (c), 4-C6H4NO2 (d)) have been synthesized by the reaction of the corresponding sulfhydryl complexes, CpRu(L)(L')SH, with chloroformates, ROCOCl, at low temperature. The bis(triphenylphosphine) complexes 1 can be converted to 3 under CO atmosphere. The crystal structures of CpRu(PPh3)(2)SCO2Bu" (1b), CpRu(dppe)SCO2Bu" (2b), and CpRu(PPh3)(CO)SCO2Bu" (3b) are reported. (c) 2006 Elsevier B.V. All rights reserved.
