Abstract

The ring expansion reaction of 1-alkynylcycloalkanols with poly[styrene(iodosodiacetate)] and iodine affords (Z)-2-(1-iodo-1-organyl)methylenecycloalkanones in moderate to good yields.

Key words - poly[styrene(iodosodiacetate)] - ring expansion - 1-alkynyl substituted tertiary alcohols - 2-(1-iodo-1-organyl)methylenecycloalkanones
