palladium‐catalyzed coupling reaction of N‐hydroxyphthalimide esters and styrenes to deliver exclusively (E)‐substituted olefins under irradiation with visible light is reported. This method tolerates N‐hydroxyphthalimide esters derived from primary, secondary, tertiary as well as benzylic carboxylic acids. Notably, Pd(PPh3)4 is employed as an inexpensive palladium source and no addition of base or classical
