Herein the progress of photochemical reactions, including photo-fries rearrangements, Norrish/Yang photo- cyclization, dimerization of 9-substituted anthracenes and asymmetric photoreactions within the confined media is reviewed and the general rules are summarized for microreactor-controlled selectivity of the pho- tochemical transformations.
