    Abstract: A pyridine-catalyzed double C–N bond cross-coupling reaction involving two benzynes with an isocyanate was carried out. The coupling reaction proceeded through a unique pathway involving the formation of an unstable carbamic acid intermediate and facile decarboxylation. Subsequent nucleophilic addition/protonation of in situ prepared amines with benzynes afforded variously substituted diaryl- and triarylamines in moderate to good yields with tolerance of a variety of functional groups.
