Abstract

 THE RITTER REACTION IS IMPORTANT CARBON–NITROGEN BOND FORMATION IN ORGANIC SYNTHESIS. THE MAIN DISADVANTAGE OF CLASSICAL RITTER THE MAIN DISADVANTAGE OF CLASSICAL RITTER PROCEDURE IS THE USE OF AN EXCESS AMOUNT OF CORROSIVE SULFURIC ACID, THUS LIMITED ITS APPLICABILITY TO COMPOUNDS CONTAINING FUNCTIONAL GROUP STABLE TO ACID. THE CLASSICAL RITTER REACTION IS REQUIRED TO SEVERAL MODIFICATIONS TO OVERCOME ITS LIMITATION[1].IN THESE PROJECTS HAVE BEEN TRIED INSTEAD OF USING ALCOHOL RESOURCES OF AN ESTER (DI-TERT BUTYL DICARBONATE) USED IN THE PRESENCE OF IONIC LIQUID ETHYL AMMONIUM NITRATE AS A CATALYST OF REACTION AND NITRILE VARIOUS TERT BUTYL AMIDES WERE SYNTHESIS SUCCESSFULLY WITH VERY GOOD YIELD. WE CONCLUDED THAT ETHYL AMMONIUM NITRATE AS THE IONIC LIQUID WITH EXTRA PROPERTIES TO BE ABLE TO CREATE THE CHEMICAL ENVIRONMENT GREEN AND AS A SOLVENT-CATALYST IS EFFECTIVE AND EFFICIENT FOR MODIFIED RITTER REACTION. THE MAIN ADVANTAGE OF THIS METHOD OF BEING NON-TOXIC CATALYST, A PRODUCT OF THE PERCENTAGE OF HIGH PURITY, EASY SEPARATION OF REACTION PRODUCTS AND SAFE CONDITIONS.
