Synthesis of functionalized mono-, di-, tri-, and tetraphosphines: Attempted application to prepare hyperbranched polymers and dendrimers built with phosphines at each branching point
The synthesis of several functionalized mono-, di-, tri-, and tetraphosphines is described. These compounds are used for the attempted preparation of hyperbranched polymers and dendrimers possessing free phosphino groups at each branching point within the structure. Theses attempts were not fully successful, but several phosphaacetylenic derivatives have been isolated.
