Laboratory Insider: A Look Inside the Organic Synthesis Lab
Ask the Expert Webinar
Presented live November 2, 2022
Step inside the Parasram Lab at New York University for a look at some of their latest research.
In this webinar, Professor Marvin Parasram will discuss data from his laboratory’s recent publication, “Anaerobic Heteroatom Transfer Reactions Using Photoexcited Nitroarenes.” The research features developments on the anaerobic cleavage of alkenes into carbonyl compounds using nitroarenes as oxygen transfer reagents under visible light. This approach is a safe and practical alternative to mainstream oxidative cleavage protocols, such as ozonolysis and the Lemieux–Johnson reaction.
As an attendee, you will learn more about:
- How a wide range of alkenes possessing oxidatively sensitive functionalities underwent anaerobic cleavage to generate carbonyl derivatives with high efficiency and regioselectivity, using the Advion Interchim Scientific puriFlash® 5.250 Preparative HPLC system.
- Mechanistic studies support that the transformation occurs via direct photoexcitation of the nitroarene followed by a nonstereospecific radical cycloaddition event with alkenes.
How this process leads to 1,3,2- and 1,4,2-dioxazolidine intermediates that fragment to give the carbonyl products, using the Advion Interchim Scientific expression Compact Mass Spectrometer. - How a combination of radical clock experiments and in situ photoNMR spectroscopy revealed the identities of the key radical species and the putative aryl dioxazolidine intermediates, respectively.Watched the video and ready to learn more?

Continuous Purification from Flow Chemistry Systems with In-Line Flash Chromatography
Recorded June 15, 2022.
Join Christopher Thomson, Researcher at Heriot-Watt University, as he shares his work expanding the tool kit of automated flow synthesis with the development of in-line flash chromatography purification.
In this webinar, you will learn:
- An introduction to flow chemistry and in-line purification technologies.
- An overview of prior continuous chromatography methods, their advantages and limitations.
- How to interface flow reactors with puriFlash automated chromatography systems.
- ‘Tips & Tricks’ for performing continuous in-line flash chromatography.
- Future prospects for developing in-line flash chromatography.
Chris completed his chemistry with biochemistry degree (MChem, 1st Class) at Heriot-Watt University, Edinburgh, in 2018 and was recipient of the ‘William H. Perkin Prize’ for excellence in organic chemistry. He was then awarded a PhD scholarship through the EPSRC funded centre for doctoral training in critical resource catalysis (CRITICAT), under the joint supervision of Dr Filipe Vilela and Dr Ai-Lan Lee.
Chris’ research focuses on the development and implementation of enabling technologies – especially flow chemistry – to enhance heterogeneous photocatalysis for organic synthesis.
He has published several papers on the development of flow systems featuring enabling technologies, such as: in-line NMR spectroscopy, in-line UV-Vis. spectroscopy, static mixing photocatalyst monoliths produced via functional material additive manufacturing, and most recently, reported the first example of continuous in-line flash chromatography – which will be the subject of this webinar.
