The halogen atom transfer radical cyclization of a N-allyl-N-benzyl-2,2-dihaloamides to 2-pyrrolidinones has been carried out in high yields under mild conditions, in a reaction promoted by CuCl-TMEDA or Fe0-FeCl3 in acetonitrile or N,N-dimethylformamide, respectively.

Electrochemical reduction of trichloromethylbenzene at a mercury electrode in DMF/TBABF4 in the presence of acetic anhydride gives 1,2-diacetoxy-1-phenylpropene as major product; minor products are dichloromethylbenzene and dimerized products.During the reduction 1,1-dichloro-1-phenyl-2-propane and 2-acetoxy-1-chloro-1-phenylpropene can be detected.With sodium perchlorate as supporting electrolyte 1-chloro-1-phenyl-2-propanone and 1-acetoxy-1-phenyl-2-propanone are formed; these products are also formed during the reduction of benzal chloride in the presence of acetic anhydride.Reductive carboxylation of trichloromethylbenzene gives 2,2-dichloro-2-phenylacetic acid.

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.
