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.
Physical, chemical, and isotopic (atomic) labels

, (2008/06/13)
Chemical or isotopic labels are added to, e.g., a potentially lethal drug formulation, to generate a unique chemical fingerprint. Combinations of chemical additives are mixed with the drug to aid in their isolation and identification, especially when such drugs are used for illicit purposes. When stable isotopes are incorporated into lethal drugs, the labeling process conveys a very unique internal chemical signature and greatly aids in the identification of the parent drug in body fluids and tissues. When heath-care providers become aware that certain drugs can now be easily tracked and identified in a victim, individuals may be reluctant to utilize these agents for ill purposes.
