Recent advances in palladium-catalyzed reactions in water

As a reaction medium, water can improve the conversion and selectivity of the organic reaction through its own properties (such as polarity, high dielectric constant, etc.). This review will focus on palladium-catalyzed reaction in water and the relevant articles published in the past 2 years in the field will be summarized. Depending on the type of the reaction, this review is divided into three parts: cyclization reaction, Suzuki coupling reaction, and miscellaneous reaction.
