The ability of Staphylococcus aureus to adapt to the toxic action of 1,2,4-triazole and its sulfuryl derivates has been studied. A positive correlation is found between the lipophilicity and toxicity of substances. It is established that methylated derivates are more toxic than substances without methyl radicals. St. aureus species grown on a medium containing triazolides in a nontoxic dose become resistant to highly toxic doses of these substances. The possible mechanisms of St. aureus adaptation to triazolides are discussed.

ABSTRACT A protocol for the synthesis of N-sulfonyl imidazoles and triazoles has been achieved using N-Fluorobenzenesulfonimide as a sulfonyl source. This reaction proceeded well in the absence of strong bases and catalysts, providing a convenient alternative method for the preparation of N-sulfonyl imidazoles as well as triazoles.

A new and convenient procedure is developed for the preparation of N-sulfonylbenzotriazoles from sodium sulfinates and benzotriazoles using molecular iodine as catalyst via the SN bond formation reaction. This catalytic radical sulfonylation proceeds efficiently in air at room temperature under neutral conditions, and in short reaction time, to afford the corresponding N-sulfonylbenzotriazoles in good

ABSTRACT A convenient procedure is developed for the preparation of N-sulfonylbenzotriazoles from sodium sulfinates, benzotriazoles, and sodium bromide in the present of m-chloroperbenzoic acid as oxidant. This radical sulfonylation proceeds efficiently at room temperature under neutral conditions, affording the corresponding N-sulfonylbenzotriazoles in moderate to good yields in a short time. GRAPHICAL
