bioactive and medicinally relevant molecules. Historically, the formal hydroazidation of simple activatedolefins and styrenes has proven difficult due to the inherent propensity of these compounds to oligomerize. Herein is disclosed a method for the anti-Markovnikov hydroazidation of activatedolefins, catalyzed by an organic acridinium salt under irradiation from blue LEDs. This method is applicable

report the B(C6F5)3-catalyzed E-selective isomerization of alkenes. The transition-metal-free method is applicable across a diverse array of readily accessible substrates, accessing a broad range of synthetically useful products containing versatile stereodefined internal alkenes. Synthetic and computational mechanistic studies indicate that the isomerization proceeds along competing 1,2-hydride shift
