thank you Rapid Method of Converting Primary Amides to Nitriles and Nitriles to Primary Amides by ZnCl 2 using Microwaves under Different Reaction Conditions In continuation of our work on ZnCl 2, [10] we report herein the use of ZnCl 2 as a catalyst for the dehydration of primary amides into nitriles and A dehydration reaction of aldoximes and amides for the synthesis of nitriles using XtalFluor-E proceeds rapidly at room temperature in an environmentally benign solvent with only a slight excess of the dehydrating agent. Displacement of chloride by the amide oxygen gives the O-sulfonylated intermediate. What is the mechanism for dehydration of amides to nitriles with acetic anhydride??? Nitrile functionalities are extensively applied in organic Synthesis and used for the production of pharmaceuticals, agrochemicals, and polymers1,2. A new, mild, and reversible method to convert primary amides to nitriles in good yields using PdCl2 in aqueous acetonitrile is described. all the recent synthetic developments in Dehydration of amides to Nitriles. Notes: Note that the net effect of this reaction is to remove two H atoms and one O from the amide. Description: Primary amides can be converted to nitriles with a dehydrating reagent such as P2O5 .
