We report on a structural (multinuclear NMR), thermodynamic (pK(a)), and kinetic (Marcus intrinsic reactivity) study of the ionization of benzylic carbon acids activated by an exocyclic (alpha) SO(2)CF(3) group and SO(2)CF(3) or S(O)(=NSO(2)CF(3))CF(

Condensation of various dienes with fluoroalkyl vinyl sulfoxides was studied. Four diastereoisomers were obtained in the case of cyclopentadiene and their structures were assigned by 2D NMR experiments. Diels-Alder cycloaddition occurred with cyclohe

We have developed a new method of perfluoroalkylation of thiols, using a mixture of sodium formate/sodium sulfite to generate a sulfoxylate radical anion. This method is compatible with alcoholic functionality and was applied to mercaptoethanol. The

Trifluoromethaneselenenyl chloride is prepared by a two-step procedure with an 85% overall yield. Benzyl trifluoromethyl selenide is formed from dibenzyl diselenide and trifluoromethyl iodide in the presence of sodium hydroxymethanesulfinate. The ben

Isotope effects on the chemical shift (IECS) of 19F bonded through two or three bonds to the isotopes 35Cl and 37Cl are reported for a wide range of two-carbon chlorofluorocarbons (and, for a few cases, with the isotopes 79Br and 81Br, for two-carbon

Michael addition of alkoxides or diethyl methylmalonate to 2-chloroacrylonitrile provides functional carbanions which are able to react with 1,3-dinitrobenzene following a vicarious nucleophilic substitution to give new substituted nitroarenes.

Direct perfluoroalkylation of aliphatic thiols was performed in the presence of sodium hydroxymethanesulfinate (Rongalite). Reaction of mercaptoalkanoic esters with trifluoromethyl bromide gave the corresponding trifluoromethylthio ethers. Condensati
