O-Phenylenediamine → Benzimidazole

Participants

Reaction Steps

The first step (a) illustrated on FIG. 15 is a reaction between ortho phenylene diamine 23 and hexafluoropropene 24 in autoclave for 24 hours and the resulting derived product is obtained with a good output (75%). This reaction does not make it possible to obtain a fluorinated vinyl monomer with benzimidazole functionality 21b, but to obtain 2-(1,1,1,2-tetrafluoroethyl)benzimidazole 10, after recrystallization in a water/ethanol mixture and with an output of 75%.
