  • N-substituted 3,4-alkylenedioxypyrroles, ester substituted dihydroxypyrroles and methods for synthesis of these pyrroles
    Patent number: 7799932
    Abstract: A family of N-substituted 3,4-alkylenedioxypyrrole 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-alkylenedioxypyrroles 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.
