Paragraph 0021; 0037, (2014/09/03)
A method for the synthesis of 1,3-di(chloropropyl)-5-tert-butyl benzene includes the steps of conducting Friedl-Crafts alkylation of 1,3-diisopropyl benzene by tert-butyl chloride in the presence of an alkylation catalyst to obtain 1-tert-butyl-3,5-diisopropylbenzene; peroxidizing the 1-tert-butyl-3,5-diisopropyl benzene by gaseous oxygen in the presence of a peroxidation catalyst in a basic solution to obtain 1,3-di(peroxypropyl)-5-tert-butylbenzene; reducing the 1,3-di(peroxypropyl)-5-tert-butylbenzene with a reducing agent to 1,3-di(hydroxyl propyl)-5-tert-butylbenzene; and chlorinating the 1,3-di(hydroxypropyl)-5-tert-butylbenzene to obtain 1,3-di(chloropropyl)-5-tert-butyl benzene.

Sulfides 4, 11, and 12 react with m-chloroperbenzoic acid to form apically unsymmetrically substituted sulfuranes 18-20, respectively, instead of the isomeric symmetrically substituted dialkoxysulfuranes.Rapid equilibration (ΔG*12 deg C = 14.7 kcal mol-1) of isomers of sulfurane 18 is observed and studied by (1)H NMR spectroscopy.An associative mechanism for these interconversion processes is proposed.Potassium salts of 18 and 19 are symmetrical dialkoxysulfuranes 21 and 22, respectively.Other reactions involving these sulfuranes are also reported.
