Abstract
Abstract
The three-membered phosphametallacycles
[R = o-Tol (3a), R = Ph(3b)] react with the tertiary phosphanes Me3P (4a), Me2PhP (4b) or MePh2P (4c) with ring opening and deselenation to the metallo-phosphanes fran.s-Cp(OC)2(R3P)WP(o-Tol)(R) (5a-d). Analogous reactions of the P-thioformamido- and formamido-substituted metallacycles
[R = Mes, X = S (6a); R = t-Bu, X = O (6b)] with Me3P (4a) yield in the case of 6a the tungsten-phosphane Cp(OC)2(Me3P)W-P(Mes)[C(S)N(H)Et] (7), while 6b affords the tungsten-selenophosphorane Cp(OC)2(Me3P)W-P(Se)(f-Bu)[C(0)N(H)Et] (8 ). Treatment of 7 with hydrogen chloride affords {Cp(OC)2(Me3P)W-P(H)(Mes)[C(S)N(H)Et] }C1 (9). With methyliodide, 8 is transformed into {Cp(OC)2(Me3P)W-P(SeMe)(t-Bu)[C(O)N(H)Et]}I (10)
