The Photoreactor TAK120 has proven itself valuable in industrial scale research: Researchers from the Columbia University, New York, and from Merck & Co. report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. This method enables the synthesis of amines with α-trifluoromethyl functionality: "Synthesis of Sterically Hindered Primary Amines by Concurrent Tandem Photoredox Catalysis" Nicastri, Lehnherr, Lam, DiRocco, Rovis, J. Am. Chem. Soc. 2020, 142, 2, 987 – 998. DOI: 10.1021/jacs.9b10871. Have a look at the paper here:

The Photoreactor TAK120 is a powerful device for irradiating chemical reactions with visible light. The reactor stands for conformity and reproducibility in the field of photocatalysis. Providing a maximum of 7 Watts of irradiation power per slot, the reactor can conduct up to 10 reactions simultaneously. Due to this remarkable high irradiation density, the required processing time of reported photoreactions has successfully been shortened to a fraction. An effective air-cooling system is used to cool the LEDs as well as the reactions, themselves, and keep them near room temperature. The reaction temperature can be monitored by an (optional) integrated sensor. The standard light colors are green (530 nm) and blue (455 nm). UV and IR light-systems are available on demand.


Our student team worked very hard on a product video of our Photoreactor.

With help from Prof. Dr. Oliver Tepner, who kindly provided the shooting location, we got to finish the film shooting. The video will be presented to you quite soon. Check out our facebook page for further information. Special Thanks to: Prof. Dr. Oliver Tepner Claudio Höll Rebecca Daiminger Sarah Stock

The Photoreactor TAK120 has been frequently used in Professor König's lab and was applied in their recent publication in Angewandte Chemie where they achieved the direct reduction of aromatic compounds using visible-light photoredox catalysis: "Birch-Type Photoreduction of Arenes and Heteroarenes by Sensitized Electron Transfer" Chatterjee, König, Angew. Chem. Int. Ed. 2019, 58, 2 – 8. DOI: 10.1002/anie.201905485. Have a look at the paper here:
