“…It resulted in a low selectivity and yield of 1,2-MPG . Recently, CO 2 -promoted hydration reactions catalyzed by metals or ionic liquids had attracted much attention, including the CO 2 -promoted hydration of propargylic alcohols and CO 2 -promoted hydration of ethylene epoxide. − In these reactions, CO 2 participated in the reactions but was not consumed. Accordingly, the synthesized hybrid polymer PIL@CHT was applied to catalyze the CO 2 -assisted hydration of PO.…”

Swelling is a very common phenomenon in organic substances. However, the swelling behaviors of inorganic substances had rarely been reported. In this study, a new type of swellable organic–inorganic hybrid polymer (PIL@CHT) was designed and successfully synthesized through free-radical copolymerization of polymerizable phosphonium ionic liquid monomer and vinyl-functionalized hydrotalcite (CHT). The swelling behaviors of PIL@CHT in various solvents with a wide range of Hansen solubility parameters (δT) were investigated, and PIL@CHT exhibited excellent swellable capacity in the solvents with δT > 24.4 MPa1/2. The swollen state of the hybrid PIL@CHT in water presented a network structure with a diameter of approximately 8–12 μm, and CHT particles were well dispersed to the channel of PIL. PIL@CHT was applied to catalyze the CO2-assisted hydration of propylene oxide (PO), in which a cascade reaction including the cycloaddition of CO2 and PO and the subsequent hydrolysis of propylene carbonate (PC) occurred. PIL@CHT, combining the active sites of PIL and CHT, synergistically catalyzed this cascade reaction and achieved a high yield (93.0%) and selectivity (98.2%) of 1,2-propanediol (1,2-MPG) under a low H2O/PO ratio of 1.5/1. Moreover, the catalyst could be recycled seven times without any significant loss of catalytic activities and had good substrate generality.

The C=C double bond cleavage of enaminones has been accomplished in the presence of methyl sulfonyl azide (MSA) to provide α‐hydroxyl ketones via the reaction with water. The major process of the reactions consists of the formation of a key α‐diazoketone intermediate resulting from the enaminone‐azide annulation, and a successive decomposition. Totally 22 α‐hydroxyl ketones have been synthesized with the yield range from 43 %–83 %.
