NEW Flow Chemistry Publication: A continuous-flow, two-step procedure for the preparation of a-CF3-substituted carbonyl compounds has been developed using the Uniqsis Binary Pump Module in combination with a lab built photoreactor.
The carbonyl substrates were converted in situ into the corresponding silyl enol ethers, mixed with the CF3 radical source, and then irradiated with visible light using a flow reactor based on transparent tubing and a household compact fluorescent lamp.
The continuous protocol uses Eosin Y as an inexpensive photoredox catalyst and requires only 20 min to complete the two reaction steps.
