“…In this first step, two aniline molecules undergo a gas‐phase acid‐catalyzed condensation reaction [ 14 ] yielding DPA and ammonia in a well‐known industrial synthesis route. [ 15,16 ] Further studies find that aniline converts to DPA with a selectivity and conversion of up to 98% and 36%, respectively. [ 16–18 ] The reaction proceeds via protonation of the benzene ring resulting in the formation of an anilinium ion.…”

[ 16–18 ] The reaction proceeds via protonation of the benzene ring resulting in the formation of an anilinium ion. The attack of a second aniline molecule on the anilinium ion results in the formation of a N ‐containing biphenyl cation and ammonia, which further deprotonates to diphenylamine.…”
