Microwave-assisted benzyne-click chemistry: preparation of 1H-benzo[d][1,2,3]triazoles

The benzotriazoles were prepared by three-component and two-component microwave-assisted [3+2] cycloadditions of various azides to benzyne, 3-methoxybenzyne, and 4,5-difluorobenzyne. In the three-component reaction, the aryne is generated, in the presence of an azide prepared in situ, by the reaction of an o-(trimethylsilylaryl) triflate with either CsF or KF/18-Crown-6. However, in the two-component reactions, a freshly prepared azide is added to the reaction vessel prior to aryne generation. Good to excellent yields of benzotriazoles were obtained in 15-20 min when the microwave-assisted reactions were carried out at 125 °C. These reaction times are significantly faster than similar reactions carried out using conventional heating.

Azoles. Part 43:1 reactions of N-(phenylsulphonylmethyl)- and N-(phenylsulphinylmethyl)azoles with some nitroarenes

Treatment of nitroarenes with 1-(phenylsulphonylmethyl)azoles in the KOH/DMSO system at room temperature resulted usually in the cleavage of the phenylsulphonyl group, whereas the t-BuOK/DMF system at low temperature promotes to a greater extent oxidation of the σ-adducts. When 1-(phenylsulphinylmethyl)azoles were used for the reaction only elimination of the phenylsulphinyl group was observed. (C) 2000 Elsevier Science Ltd.
