N2  - A mesoporous titanium-silicate prepared by evaporation-induced self-assembly is an efficient heterogeneous catalyst for the one-step oxidative carboxylation of styrenes with tert-butyl hydroperoxide and carbon dioxide in the presence of tetrabutylammonium bromide as cocatalyst under mild solvent-free conditions (50–70 °C, 8 bar CO2). The selectivity to cyclic carbonates reaches 69–70% at 92–98.5% substrate conversion. The catalyst can be easily recovered by filtration and reused several times without a significant deterioration of the catalytic performance. The volume yield of SC as high as 1.1 kg/L could be achieved after seven reuses
