N-Acyltriazenes serve as a tin-free and initiator-free source for amidyl radicals. Thermal decomposition of N,N′-diaryl-N-(4-pentenoyl)triazenes in refluxing toluene led to the formation of monocyclic and tricyclic lactams in satisfactory yields via 5-exo amidyl radical cyclization.
N-酰基三氮烯可作为酰胺基的无锡和无引发剂的来源。N,N′-二芳基-N-(4-戊烯酰基)三氮烯在回流的甲苯中的热分解导致通过5-外酰胺基自由基环化以令人满意的产率形成单环和三环内酰胺。
