Cluster chemistry. Reactions between metal carbonyl clusters and Lewis bases initiated by radical ions: improved syntheses of substituted derivatives of M3and M4 clusters(M = Fe, Ru, Os or Co)

Abstract

Addition of catalytic amounts of Ph2Co˙–to a mixture of the appropriate cluster with stoicheiometric amounts of Lewis base in tetrahydrofuran gave the substituted derivatives [Fe3(CO)11(L)],[Ru3(CO)12–n(L)n],[Os3(CO)11(L)], and [H4Ru4(CO)12–n(L)n][n= 1–3; L = ButNC,PR3,P(OR)3]in greatly improved yields.
