Substituted Pyrazoles

1-Chloromethyl-3,5-dimethylpyrazole hydrochloride readily undergoes nucleophilic displacement with O-, N-, or S-nu-cleophiles. 1-Phenylthiomethyl-3,5-dimethylpyrazole can be lithiated at the CH2 group and reacted with alkyl halides and carbonyl compounds. Desulfurization of the products affords a novel method of preparing N-substituted pyrazoles. Keywords: pyrazole, lithiation, chloromethylazoles, desulfurization.

Villiger Oxidation

Na2SeSO3, which can be generated in situ by the reaction of Na2SO3 with Se power, was found to be an odorless reagent for the selenenylation of alkyl halides to produce dialkyl diselenides. These products have been recently shown to be good catalysts for the Baeyer–Villiger oxidation of carbonyl compounds, for the selective oxidation of alkenes, or for the oxidative deoximation of oximes. By using aqueous EtOH as the solvent and avoiding the generation of a malodourous selenol intermediate, the selenylation reaction with Na2SeSO3 is much more environmentally friendly than conventional methods. Owing to the cheap and abundant starting materials and selenium reagents, our novel synthetic method reduces the production costs of dialkyl diselenides as organoselenium catalysts, thereby advancing practical applications of organoselenium-catalysis technologies.
