Abstract
Treatment of the ferrio-phosphane Cp(OC)(2)Fe-PPh2 (1) with Me3P (2) y ields Cp(OC)(Me3P)Fe-PPh2 (3) via GO-substitution. Reaction of 3 with methylisothiocyanate (4) leads to the formation of the adduct Cp(OC)(M e3P)Fe-PPh2-C(S)NMe (5), which is regioselectively methylated at the s ulfur atom with MeI (6a) or MeSO3CF3 (6b), respectively, to give the c ationic complexes [Cp(OC)(Me3P)Fe-PPh2-C(SMe)=NMe]I/CF3SO3 (7a,b). In contrast, protonation with CF3SO3H (8) occurs at the nitrogen atom, yi elding [Cp(OC)(Me3P)Fe-PPh2-C(S)-N(H)Me] CF3SO3 (9). The structures of 7b and 9 have been determined by X-ray diffraction analysis.
