“…Of these, photodecarboxylation reactions of phthalimides have been intensively studied 29, 36. These versatile transformations have also been used as model reactions for meso‐scale production using an advanced circulating falling‐film batch reactor 37, 38, and for continuous‐flow synthesis utilizing improvised microreactor systems 31, 39, 40.…”

Selected photodecarboxylations of phthalimides were realized under continuousflow conditions using an advanced meso-scale photoreactor. The improved efficiency, yields, and productivities of these photochemical reactions highlight the benefits of using flow as opposed to conventional batch operation modes. Flow chemistry furthermore allows for an easy combination of multiple reaction steps in series. This is demonstrated by the successful synthesis of a pharmaceutical target molecule through a tandem photochemical-thermal procedure carried out in uninterrupted flow.

“…The photodecarboxylation was first reported by Griesbeck and has subsequently been developed by Oelgemöller. 2,43,[51][52][53][54][55] It is an example of a C-C bond forming reaction, an important class of reaction in synthetic chemistry. Typically C-C bond formation employs transition metal catalysis and/or the use of stoichiometric organometallic reagents, i.e.…”

Reaction-oriented research in flow chemistry and microreactor has been extensively focused upon in special journal issues and books. On a process level, this resembled the "drop-in" (retrofit) concept with the microreactor replacing a conventional (batch) reactor. Meanwhile, with the introduction of the mobile, compact, modular container technology, the focus is more on the process side, including also providing an end-to-end vision of intensified process design. Exactly this is the focus of the current special issue "Design and Engineering of Microreactor and Smart-Scaled Flow Processes" of the journal "Processes". This special issue comprises three review papers, five research articles and two communications.Rahman and Rebrov have presented an overview of the application of microreactors in the synthesis of gold nanoparticles (GNP) [1]. Considering that reactant mixing is one of the most critical factors influencing the GNP synthesis, batch operating conditions commonly pose great limitations to both quality and scalability of the process. In contrast, synthesis in microflow overcomes this constraint and allows to individually affect the diverse elemental steps within GNP synthesis, which provides unique chances in process optimization.Choi et al. have given the state-of-the-art of the microreactor-assisted solution deposition (MASD) technique for fabricating compound semiconductors, as well as instructive insights in scaling-up the MASD process by implementing the numbering-up strategy [2]. Special focus has been given on the application of the MASD in cadmium sulfide (CdS) thin film deposition. The MASD process exhibits advantages over the conventional batch chemical solution method by enabling operation at lower temperature, enhancing reaction selectivity, reducing capital cost and providing perspectives for process scale-up.
