Five different model reactions (photodecarboxylation, inter- and intramolecular [2+2] cycloadditions, TiO2 photocatalytic reduction and type II photooxygenation) were investigated in the advanced Vapourtec UV-150 photo reactor with their conversion and throughput potentials reported. Compared to known batch reactions in laboratory reactors, significantly higher calculated productivities were achieved despite a rather small 10 mL reactor coil. The device enables rapid, convenient, reliable and reproducible flow photochemistry studies across the entire wavelengths spectrum and on flexible scales.
