Abstract

Oppfinnelsen relaterer til en fremgangsmåte for å produsere diazoalkaner, som er karakterisert ved å oppløse en diazoalkanforløper i et første løsningsmiddel, oppløse en base i et andre løsningsmiddel, tillate substansene å reagere i en reaktor mens de danner diazoalkan og fjeme diazoalkanen under redusert trykk. Oppfinnelsesfremgangsmåten er spesielt passende for å produsere diazometan.
