It is promising and challenging to achieve the effective construction of carbonates
using CO2 and a non-noble metal catalyst. Herein, selective catalytic conversion of CO2 and switchable alcohol candidates to produce linear or cyclic carbonates and α-hydroxy
ketones via effective zinc catalyst was developed. A series of primary alcohols and
cyclohexanol, 1,2-diols, and water can serve as nucleophiles to give alkyl or aryl
2-substituted-3-oxobutan-2-yl carbonates, substituted 1,3-dioxolan-2-ones, 3-substituted
3-hydroxybutan-2-ones, respectively with excellent selectivity and high yields.
