Radical chemistry in flow

The past two decades have witnessed a rapid growth in flow-based organic synthesis and synthesis involving radical reactions in flow systems is no exception. Flow microreactors have large surface-to-volume ratios that become available by the employment of tiny channels, and this allows radical reactions to occur with efficient heat transfer and diffusion. Flow photomicroreactors with thin, glass-made channels allow for efficient light penetration, which enables highly efficient photo-radical reactions. This chapter highlights recent advances in both thermal and photo-induced radical reactions, which have achieved increased efficiency by using flow reaction systems.
