Professor Wirth and his team at Cardiff have used a Vapourtec E-series to safely generate and handle a highly reactive diazolithium species that reacts highly exothermally. The Vapourtec E-Series allows Professor Wirth to access this highly energetic chemistry, which would be very challenging in batch.

The recent 8th Symposium on Continuous Flow Reactor Technology for Industrial Applications, held in Delft, Netherlands, proved a great success for Vapourtec with significant levels of interest in the R-Series system and UV-150 photochemical reactor.

Flow chemistry will be a key theme at this year’s 20th UK Automated Synthesis Forum (Duxford, November 7th-8th) with Vapourtec showcasing the R-Series, the world’s most published flow chemistry system.

Vapourtec will be demonstrating their easy-MedChem flow chemistry system and UV-150 photochemical reactor at the Challenges in Catalysis for Pharmaceuticals and Fine Chemicals V event (London, November 2nd) organized by the RSC Applied Catalysis Group.

Professor Steven Ley and his team at Cambridge University have demonstrated how visible light can be used to perform complex photoredox cross-couplings in continuous flow. In an elegant paper, Professor Ley and his team have again shown how continuous flow chemistry can be a tool for new synthesis and reaction efficiency.

Vapourtec is targeting further growth in demand for its flow chemistry technology from the US market following their recent presence at the ACS (American Chemical Society) 252nd National Meeting and Exposition in Philadelphia in August.

“Customer support is Vapourtec’s number one priority and we are pleased to unveil our new look application support team following two recent, key appointments,”.

Vapourtec (Cambridge, UK) will be demonstrating their easy-Photochem flow chemistry system and UV-150 photochemical reactor at JCO 2016 (Journees de Chimie organique 2016, Palaiseau, France 7-9 Sept).

Vapourtec will be exhibiting and demonstrating at the 2016 IMRET (International Conferences on MicroREaction Technology) conference in Beijing (Sept 11-14). As well as Product displays (Booth 10), Vapourtec’s continuous process technology will be highlighted in two speaker presentations.

The Vapourtec E-Series has been at the core of a recent paper describing continuous flow chlorine generation. In the exciting paper, the Kappe group of the University of Graz, Austria, has used the Vapourtec E-Series to develop in situ chlorine generation in continuous flow. The group have been able to liberate elemental chlorine in small quantities from common reagents to saturate an organic phase. The chlorine rich organic phase was used by the Kappe group to chlorinate silanes, oxidise alcohols, and making use of the Vapourtec UV-150 continuous flow photochemical reactor, chlorinate a range of substituted toluenes. This is a clear demonstration of how flow chemistry can be used to reduce the risks of working with such a potentially hazardous reagent as chlorine, with the easy to use Vapourtec E-Series an ideal system for flow investigations.

An exciting new approach to nickel catalysed C-N coupling has been explored by Corcoran et al. of Professor MacMillan’s group, Princeton University. The new method uses nickel(II) salts that are reduced in situ to nickel(0) under mild conditions using photoredox catalysis. The Vapourtec UV-150 continuous flow photochemical reactor has been at the heart of the group’s progress in using this new method in continuous flow, resulting in high chemical yields at a fraction of the batch reaction time.

UK-based flow chemistry engineering specialists Vapourtec will be showcasing their easy-MedChem system and UV-150 photochemical reactor at the forthcoming 252nd ACS National Meeting and Exposition in Philadelphia (August 21-23).

Vapourtec’s UV-150 continuous photochemical reactor has been used in a scale-up of an innovative approach to trifluoromethylation, with exciting results. Professor Stephenson’s group at Michigan University have developed a photochemical trifluoromethylation method generating CF3 radicals in situ, however the batch scale-up suffered from common barriers such as poor light penetration. Using the Vapourtec UV-150 photochemical reactor a significant increase in yield was observed, demonstrating how the use of a commercial continuous flow photochemical reactor can have significant advantages when applied to novel synthesis.
