The halothane-derived peroxyl radical CF3CHClO2. has been generated in aqueous solutions by pulse radiolysis.Absolute rate constants for the reduction of halothane (2-bromo-2-chloro-1,1,1-trifluoroethane) by hydrated electrons, hydrogen atoms, and propan-2-ol free radicals have been determined to be k 1.4E10, 3.8E8, and 7.6E7 l mol-1 s-1, respectively.The predominant product radical CF3CHCl rapidly adds O2, and an estimate of k 1.3E9 l mol-1 s-1, has been obtained for the absolute rate constant of this reaction.The resulting peroxyl radical CF3CHClO2. has been found to react rapidly with a variety of nucleophilic compounds such as 2,2'-azinobis(3-ethylbenzthiazoline-6-sulphonate), the phenothiazines promethazine, chlorpromazine, and metiazinic acid, the vitamins C and E, and propyl gallate.The absolute rate constants for these reactions are found to be generally lower than for corresponding reactions of the carbon tetrachloride-derived radical, CCl3O2..

Compounds of the formula STR1 wherein each X, which may be identical or different from the other X, is oxygen or imino; R1 is hydrogen, fluorine, chlorine or bromine; R2 and R3, which may be identical or different from each other, are each hydrogen; unsubstituted or mono-substituted alkyl of 1 to 6 carbon atoms, where the substituent is phenyl or dialkylamino with 1 to 3 carbon atoms in each alkyl moiety; pyridyl; or cycloalkyl of 5 to 7 carbon atoms; R2 and R3, together with each other and the nitrogen atoms to which they are attached, are pyrrolidino, piperidino, hexamethyleneimino, morpholino, N-aryl-piperazino or N-(alkyl of 1 to 3 carbon atoms)-piperazino; A is cycloalkylene of 5 to 7 carbon atoms; unsubstituted or substituted alkylene of 2 to 10 carbon atoms, where the substituents are one to two alkyls of 1 to 3 carbon atoms each, one to two carbalkoxys of 2 to 4 carbon atoms each, one to two phenyls, one to four hydroxyls, one halomethyl, one hydroxymethyl, one alkanoyloxy of 1 to 18 carbon atoms, one alkanoyloxymethyl of 1 to 18 carbon atoms in the alkanoyl moiety or one STR2 where R1, R2 and R3 have the meanings previously defined; or alkylene of 2 to 10 carbon atoms interrupted by oxygen, sulfur, sulfoxide, sulfonyl, phenyl, cyclohexyl, pyridyl, piperazino or unsubstituted or substituted imino, where the substituent on the imino group is alkyl of 1 to 6 carbon atoms, phenyl or phenylalkyl of 1 to 3 carbon atoms in the alkyl moiety; B is the acyl residue of an antiphlogistic carboxylic acid; and their non-toxic, pharmacologically acceptable acid addition salts. The compounds as well as their salts are useful as anti-inflammatories.
