One Pot Synthesis of Side Chain Fluorinated Heterocyclic Compounds by Microwave Irradiation

2- Or 4-Difluoronitromethyl and 2- or 4-fluoronitrobenzyl substituted pyridines, quinolines, phenantheridine, benzothiazol and benzoxazol were synthesized by reaction of the corresponding nitro compounds in the presence of 1-chloromethyl-4-fluoro-1,4- diazoiabicyclo[2,2,2]octane bis(tetrafluoroborate) (Select-Fluor) and ammonium acetate as a base under microwave irradiation.This method is very efficient and the yields were significantly improved in comparison to the previous reports
