Functionalized phosphines : synthesis, reactivity and transition metal chemistry

Ten-membered heterocycles of the type PhN(PCl2){OC6H2(R)(2) (mu-S(CH2))((R)(2)-C6H2O-)} (R = Me, Pr-i or Bu-t) have been prepared and their transition metal chemistry is explored. Functionalised phosphines react with transition metals to give interesting metallacycles. Several Group 6, ruthenium, platinum metals and novel titanium(TV) metallacycles have been structurally characterized
