摘要:
A family of N -substituted 3,4-allcylenedioxypyrrole includes monomers for of formula (I) electropolymerization to conjugated polymers and key intermediates for the preparation of the monomers. The preparation of the //-substituted 3,4-aJkylenedioxypyrτoles is carried out via a synthetic intermediate, an ester substituted dihydroxypyrrole. The synthetic method to prepare the //-substituted 3,4-alkylenedioxypyrrole intermediates and ultimately the N- substituted 3,4-alkylenedioxypyrrole monomers begins with a reaction to form the ester substituted dihydroxypyrrole.
