Metal-Free [2+2]-Photocycloaddition of Unactivated Alkenes Enabled by Continuous Flow Processing We report a continuous flow approach generating bicyclic cyclobutanes from unactivated alkenes in a metal-free manner that is inspired by the Kochi-Salomon reaction. A filtered Hg-lamp in combination with a simple flow set-up and acetone as UV light-absorbing co-solvent are crucial for this method thus showcasing attractive features for further exploitations.

Multiphase Photochemistry in Flow Mode via an Integrated Continuous Stirred Tank Reactor (CSTR) Approach A new photochemical CSTR system capable of handling solids in scaled continuous processes is presented. High-power UV-LEDs are integrated in these CSTRs containing an insoluble base that aids in generating pyrazolines via cycloaddition between alkenes and in situ generated diazo species.
