Abstract

Abstract Arsane und Stibane, LX [1]. Ferrio-(thiocarbamoyl)phosphane Cp(OC)2Fe-P(Mes)[C(=S)-N(R)H] (R = Me, Et, f-Bu): Aufbau aus dem Ferrio-mesitylphosphan Cp(OC)2Fe-P(Mes)H und Organoisothiocyanaten sowie Quaternisierung mit Alkylhalogeniden und Oxidation mit Schwefel Transition Metal Substituted Phosphanes, Arsanes and Stibanes, LX [1]. Ferrio-(thiocarbamoyl)phosphanes Cp(OC)2Fe-P(Mes)[C(=S)-N(R)H] (R= Me, Et, r-Bu): Build-up from the Ferrio-mesitylphosphane Cp(OC)2Fe-P(Mes)H and Organoisothiocyanates, Quatemization with Alkyl Halides and Oxidation with Sulfur The ferrio-phosphane Cp(OC)2Fe-P(Mes)H (4), obtained by deprotonation of the me-sitylphosphane iron complex {Cp(OC)2 [H2(Mes)P]Fe}BF4 (3), reacts with the organoiso­ thiocyanates RNCS (R = Me, Et, Ph) (5a -c) to give the functionalized ferrio-phosphanes Cp(OC)2Fe-P(Mes)[C(=S)-N(R)H] (6a-c). Quatemization of 6a,b at the phosphorus atom with the alkyl halides R′-Hal (R1 = Me, Et, CH2 Ph) (7a-c) yields the complexes {Cp(OC)2Fe-P(Mes)(R′)[C(=S)-N(H)(R)]}Hal (8a-d), whereas oxidation with elemental sulfur affords the ferrio-thiophosphoranes Cp(OC)2Fe-P(=S)(Mes)[C(=S)-N(R)H] (R = Me, Et) (10a,b). 10b is alkylated with Mel to give {Cp(OC)2Fe-P(SMe)(Mes)[C(=S)-N(Et)H]}I (11). The structure of 8b has been determined by X-ray analysis.
