Mechanistic studies on the diazo transfer reaction
摘要:
The mechanism of the diazo transfer reaction which converts amines to azides has been studied with labeled amino acids and labeled imidazole-l-sulfonyl azides. Retention of amine nitrogen in the amine, and transfer of the two terminal nitrogen atoms of the imidazole-l-sulfonyl azide to the product, were unambiguously established. (C) 2014 Elsevier Ltd.
