Interaction with Organometallic Fragments

As (T and n activated hydrocarbons, phenylenes should be susceptible to interaction with metal fragments. This notion is already home out with 1, which readily undergoes metal-promoted ring openings [16a, 21, 106] and n complexation [16a, 107]. A systematic comparison of the reactivity of higher phenylenes with transition metal complexes is yet to be executed therefore, the following provides simply a summary of what has been done so far.

The phosphorus atom of the cyclophosphazene ring can also be involved in interaction with transition metal atoms either by a coordinate or by a covalent linkage. The former occurs with hydridocyclo-phosphazenes by a tautomerization of the P-H to result in a P(III) center (222). The covalent mode of linkage occurs by the reaction of the appropriate organometallic or metal fragment with the halo-genocyclophosphazenes (223).
