The relative rate constants for the reactions of dichlorocarbene with a series of alkoxy- and halogen-substituted styrenes were determined.It was established that these values correlate with the difference between the energies of the HOMO of styrene and t

Anion of ketones, sulfones and esters were α-chlorinated by carbon tetrachloride under conditions of phase transfer catalysis (PTC).Alcohols were unreactive.The observed products show that secondary reactions took place in many cases.The chlorination of the sulfone cis-2,5-diphenyltetrahydrothiophene-1,1-dioxide (1) occurred with inversion to give trans-2,5-dichloro-2,5-diphenyltetrahydrothiophene-1,1-dioxide (2).The structures of cis-1 and trans-2 were determined by X-ray diffraction.The reaction conditions are also applicable to brominations using bromotrichloromethane.
