accordance with the experimental outcomes. Keywords: Ionic liquid, Chloromethylation, Aromatic hydrocarbons, DFT, Solvent effects 1. INTRODUCTION Chloromethyl substituted aromatic hydrocarbons are promising key intermediates because of easy transformation to many chemicals such as fine-chemicals, pharmaceuticals, and polymers. The chloromethylation of aromatic hydrocarbons has been documented in previous papers

A process for the preparation of perfluoroalkyl sulfenyl chloride; said process comprising i) reacting a compound of formula (I) wherein R represents an aromatic group with or without a substituent; and R' represents a halogen, with at least one fluoride compound and thiophosgene in a solvent to obtain a reaction mass; ii) pulverizing the reaction mass with the help of beads to obtain a mixture containing trifluoromethyl thiomethyl benzene derivative; iii) isolating the trifluoromethyl thiomethyl benzene derivative from the mixture; iv) distilling the trifluoromethyl thiomethyl benzene derivative to obtain a purified trifluoromethyl thiomethyl benzene derivative; v) dissolving the purified trifluoromethyl thiomethyl benzene derivative in a solvent selected from the group consisting of dichloromethane, toluene, benzene, ethylene dichloride, mono chloro benzene, carbon tctra chloride, ortho dichloro benzene and tri chloro benzene; and vi) cleaving the trifluoromethyl thiomethyl benzene derivative by selective chlorinolysis by passing chlorine gas at a temperature in the range of about -10 to about 30°C to obtain perfluoroalkyl sulfenyl chloride
