Reactivity of the unco-ordinated sulphur atom in monodentate dithiocarbamates: formation of the heterometallocycles FeS2C2 by reaction of KCN with [(η5-C5H5)Fe(CO)2{η1-SC(S)NR2}] and X-ray crystal structure of the benzoylaion porduct [η5-C5H5)Fe(CO){SC(NEt2)(SCNCOPh)}]

Abstract

The complexes [(η⁵-C₅H₅)Fe(CO)₂{η¹-SC(S)NR₂}](R = Me or Et) react with KCN in methanol to give the five-membered-metallocycles K[(η⁵-C₅H₅)[graphic omitted]N)}](2) which can be acylated by PhCOCl giving [(η⁵–C₅H₅)[graphic omitted]NCOPh)}](3) which had been characterized by X-ray diffraction for the complex with R = Et.
