In spite of its importance, the diazo transfer reaction has not been mechanistically elabo- rated. The first mechanistic proposal was made in 1967 by An- selme and co-worker.14According to this mechanism, the amine anion reacts with a tosyl azide giving a triazene anion intermediate which ...
Diazo (-N-2) transferS(N)i mechanismLabeled imidazole-l-sulfonyl azideThe mechanism of the diazo transfer reaction which converts amines to azides has been studied with labeled amino acids and labeled imidazole-1-sulfonyl azides. Retention of amine nitrogen in the amine, and transfer of the ...

mechanism requires further investigation, based on current experimental results, it is reasonable to speculate the formation of active reaction intermediate upon mixing1aand1a′(such asH). This intermediate would generate nitrogen radicalIand/or carbon radicalCvia single electron transfer (SET) process ...
