Nuclear heptylation and cyclopentylation of phenol and anisole

ABSTRACT

Thermal decomposition of 1-, 2-, 3- and 4-heptyl toluene-p-sul-phonates and cyclopentyl toluene-p-sulphonate in presence of phenol or anisole at 130-135 degree give different ortho- and para- substituted isomers. Skeletal isomerisatian of the heptyl group was observed where different isomeric 1-, 2-, 3- and 4 phenyl aromatics were obtained. The isomers were identified and estimated quantitatively by gas-liquid chromatography
