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