An organic acridinium salt catalyzes an anti-Markovnikov hydroazidation of activated olefins under irradiation from blue LEDs. This method is applicable to a variety of substituted styrenes and several vinyl ethers, yielding synthetically versatile hydroazidation products in excellent yield, whereas terminal styrenes provide hydroazidation products in moderate yields.
