The catalytic activity of metal-organic frameworks (MOFs) towards the transesterification of dimethyl carbonate with ethanol has been unprecedented assessed. The relation between the catalytic activity and the amount of base active sites has been proved as well as the inability of the Lewis acid sites alone to catalyze this transesterification. The synergic effect of both acid and base sites cannot be completely excluded and a plausible reaction mechanism has been proposed. MOF-808 resulted to be more efficient than every heterogeneous commercial catalyst. MOF-808 can be recycled up to 4 times with exceptional retention of both catalytic activity and crystal structure.
