Straightforward Approach to Synthesize 3,3'-Bipyrroles by Oxidative Homocoupling of 1,2,5-Trisubstituted Pyrroles
A method is developed for efficient and straightforward synthesis of 3,3'-bipyrroles by oxidative C-H homocoupling of 1,2,5-trisubstituted pyrroles in the presence of FeCl3 in a mixture solvents of CH2Cl2 and MeNO2.
