The use of light as a source for the activation of reactants can be a sustainable alternative to the conventional use of thermochemical activation , for instance for crosscoupling reactions . Light can also be used to access reactive intermediates under milder conditions, e.g., the photocatalytic pathway to generate singlet oxygen or trifluoromethyl radicals . Various studies have already illustrated the potential for the synthesis of fine chemicals and pharmaceuticals through photochemical means ; however, one of the challenges which prevents the ubiquitous use of this technology is that organic molecules tend to only absorb photons in the ultraviolet (UV) region. With energy efficient UV light sources being developed, this issue can soon be circumvented, but other challenges such as the presence of unproductive decomposition and the need for the specially designed reactors which can safely handle high intensity UV radiations, remain . Various solutions have been proposed to improve on these apparent limitations in photochemistry. For instance, an alternative to using UV activation is the use of visible light photocatalysis . This method involves the activation of metal complexes or organic dyes by light and the subsequent single-electron transfer or energy transfer from/to the substrate through various pathways . Furthermore, the combination of photochemistry with microflow reactors, has shown promise for the wide spread application of photochemical reactions . These reactors not only improve on the safety but also improve mass transfer and light penetration, leading to an accessible method for the continuous production of chemicals through photochemistry.
