提高化学反应的选择性始终是化学家关注的热点.本工作以光Fries重排反应、Norrish/Yang光环化反应、9-取代蒽衍生物的光二聚反应以及不对称光化学反应为例,结合近年来在受限介质中光化学反应研究的最新进展,总结了利用受限介质控制化学反应选择性的一般规律.
The selectivity of the photochemical reactions is always an important concern of chemists. Herein the progress of photochemical reactions, including photo-fries rearrangements, Norrish/Yang photocyclization, 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 photochemical transformations.
