Cycloaddition at 254 nm

2 ml reaction in 4 ml quartz vial (HCK1021-01-052) equipped with Teflon septa cap. 0.01 M maleimide with 1.5 equiv. 1-hexyne in acetonitrile sparged with nitrogen and irradiated with 254 nm LED (HCK1012-01-016). 56% conversion observed after 4 hours.

(4X) 400 mg scale reactions in 20 ml vials

Reaction performed at 400 mg scale per vial (10 ml reaction volume) in 20 ml scintillation vial with Teflon cap and stir bar.  Reaction performed under at 0.2 M in DMA. 4x 20 ml vials placed in PhotoRedox UV/Vis with 4x 365 nm LEDs (EvoluChem HCK1012-01-029).  74% conversion after 6 hours at 50°C

 

 

IR Temperature Monitoring

Monitoring the temperature of a photochemical reaction can be difficult and error prone based on how the temperature is being determined and the type of temperature in the probe.

Upon irradiation with high powered light from LEDs, the vial, solvent, reaction, photoreactor and the temperature probe itself can increase in temperature.  For the purposes of safety, all of these measurements are important.  To understand our chemical reaction, what is most important is the true temperature in the solution.

The instrument uses a IR probe to accurately measure temperature while the reaction is being irradiated was determined.
