Oxidative potential of trans‐3,5‐dihydroperoxy‐3,5‐dimethyl‐1,2‐dioxolane (DHPODMDO) has been explored in the facile thiocyanation of anilines and indoles through the efficient and in situ generation of SCN+ ion from sodium thiocyanate. The reactions proceed with regioselectivity under mild conditions at room temperature to afford the respective thiocyanate derivatives in excellent yields and low reaction times.

<p>The synthesis of 1,4-disubstituted-1,2,3-triazoles from alkyl azides and terminal alkynes at room temperature and under microwave heating was attained using Cu(I), generated <em>in-situ </em>from copper(II) sulfate and phenylboronic acid, as catalyst. Twelve new triazoles were obtained in moderate to good yields (53-98%), and the products were obtained by crystallization from the mixture reaction without further purification.</p>
