Oxalic acid modified Hβ (OA-Hβ) zeolite is found to have better catalytic performance than Hβ zeolite in the Friedel-Crafts hydroxyalkylation of anisole with chloral. This is attributed to the increase of weak and moderately-strong acid sites, caused by oxalic acid modification. Furthermore, it is believed that the carbonaceous deposits on the acid sites and the blockage of the pores, together with poisoning by chlorinated materials, are responsible for the deactivation of OA-Hβ zeolite, as indicated by NH3-TPD, BET, SEM, TG and XPS measurement results. Moreover, partial regeneration of OA-Hβ zeolite can be achieved via subsequent calcination.

Electrochemical transformations of DDT into oxygen-incorporated products, amides and esters, catalyzed by a B12 derivative, heptamethyl cobyrinate perchlorate, have been developed under aerobic conditions. The dechlorinative oxygenation of DDT forms the acyl chloride as an intermediate for the synthesis of the amide and ester in the reaction with the amine and alcohol, respectively. This electrochemical method demonstrated with 20 oxygen-incorporated dechlorinated products up to 88% yields with 15 new compounds and was also successfully applied to the conversion of methoxychlor to an amide and ester.
New synthetic approach to phenylmethanesulfonamide derivatives on the basis of Phenyl-N-(2,2,2-trichloroethylidene)-methanesulfonamide

The reaction of N,N-dichlorophenylmethanesulfonamide with trichloroethylene gave a new representative of highly electrophilic N-sulfonyl-substituted polyhalogenated aldehyde imines, phenyl-N-(2,2,2-trichloroethylidene) methanesulfonamide. High reactivity of the product was demonstrated by alkylation of toluene, anisole, thiophene, and 2-chlorothiophene. Pleiades Publishing, Ltd., 2012.
