Most of the steps in the mechanism are reversible, especially the proton transfers. So, the exact source of a proton doesn't matter, as that proton might have been exchanged with other protons many times before. Except for the actual rearrangement (i.e. the isocyanate forming step), most are reversible steps. – Eashaan Godbole. ihg anrccAn example of an aminolysis reaction is the replacement of a halogen in an alkyl group (R−X) by an amine (R'−NH2) and the elimination of hydrogen halide (HX). Another common example is the reaction of a primary amine or secondary amine with a carboxylic acid or with a carboxylic acid derivative to form an amide. This reaction is widely used, especially in the synthesis of peptides.
