Abstract

In reaction of 4′-arylspiro[1,2,3,4-tetrahydronaphthalene-2,3′-(1′-pyrazolin)]-1-ones with N-chlorosuccinimide formed spirocyclic substituted 3-chloro-1-pyrazolines that lost nitrogen at heating transforming into spirocyclic chlorocyclopropanes. The reaction of the same pyrazolines with chlorine led to the formation of spirocyclic gem-dichlorocyclopropanes.
