发明名称 METHOD OF MAKING PYRROLE DERIVATIVES
摘要 Heterocyclic nitrogen compounds, especially aziridine and pyrrole derivatives, are formed by addition of organic acid chlorides at the carbon double bond of single-unsaturated hydrocarbon chlorinated at the carbon atom adjacent to the double bond, said addition taking place in the presence of a Lewis-acid at low temperatures. The obtained dichloroketone is reacted in a second stage with amines or ammonia to form the heterocyclic compound. At temperatures above 100 DEG C pyrrole derivatives are obtained; below 100 DEG C aziridine derivatives are formed. Heterocyclic nitrogen compounds with various substituents can be prepared from the correspondingly selected base substances.
