FLUORINATED ALKYL COMPOUND DERIVATIVES AND PROCESS FOR PREPARING SAME

摘要

Fluorinate alkyl ketone compound represented by general formula(III) thiophenol in the presence of Lewis acid selected from catalysts such as aluminum chlorinate, titanium(IV) chloride, ferric chloride, etc., to yield fluorinated alkyl ketal represented by general formula(I) in solvents which do not affect reaction. Dithioketal is reduced by reductant such as hydrogenated aluminum lithium, hydrogenated sodium borate, etc., in solvent such as ether, tetrahydro furan, benzene alone or mixture thereby.
