A 3D-printed polypropylene (PP) continuous-photoflow cell based on a modular cartridge system was developed for the photo-oxygenation of 7-aminothieno[3,2-c]pyridin-4(5H)-ones, using ambient air as the sole co-reactant. This strategy takes advantage of the versatility of 3D-printing to construct cost-effective meso-scale reactors. In addition to scalability, a short residence time (tR 2 min) in 100-W blue LED light that minimizes the formation of dark, insoluble decomposition products is a tangible benefit of this technology.

In this work, selectivity-controllable base-promoted transition-metal-free borylation and dehalogenation of aryl halides are described. Under the conditions of borylation, the dehalogenation which emerges as a competitive side reaction has been well-controlled by carefully controlling the borylation conditions. On the other hand, the dehalogenation using benzaldehyde as a hydrogen source has also been accomplished. The applications of direct radical borylation and dehalogenation of aryl halides demonstrate their synthetic practicability in pharmaceutical-oriented organic synthesis. Based on the experimental evidences, the tBuOK/1,10-Phen-triggered radical nature of both competitive reactions has been revealed.
