Iron-based pre-catalyst supported on polyformamidine for CC bond formation

In the present study the incorporation of iron into an organic polymer, composed of formamidine subunits [RN&z.dbd;C(H)NHR], has been examined. The catalytic ability of the recyclable material was investigated in the iron-catalyzed formation of CC bonds. After optimization of the reaction conditions, excellent yields and chemoselectivities were feasible. In the present study the application of a recyclable heterogeneous catalyst based on iron supported on polyformamidine was demonstrated in CC bond formation reactions.
