THE BASE-INDUCED DECOMPOSITION OF ETHYL N-(o-AZIDOARYL) CARBAMATES. AN UNEXPECTED FORMATION OF AZO-COMPOUNDS.
Smalley, Robert K.,Stocker, Antony W.
, p. 1389 - 1392 (1984)
A mechanistic rationale is offered to explain the formation of dihydrobenzimidazoles and azo-compounds in the base-induced (NaH-DMF) decompositions of ethyl N-(o-azidoaryl) carbamates.
