Abstract

Reaction of 4,11-diaryl-1,2,8,9-tetraazadispiro[4.1.4.3]tetradeca-1,8-dien-6-ones and  -dispiro-[4.1.4.2]trideca-1,8-dien-6-ones with chlorine  gives  substituted  dispirocyclic compounds containing a 3-chloro-1-pyrazoline fragment which loses nitrogen on heating to give spirocyclic  chlorocyclo-propanes.
