In Situ FTIR Spectroscopic Monitoring of Electrochemically Controlled Organic Reactions in a Recycle Reactor.
نویسندگان
چکیده
An electrochemical cell coupled with a recycle loop through a transmission FTIR cell is employed in studies of two free radical organic reactions, the oxidation of allylic alcohols and the trifluoromethylation of heteroarenes. Rapid mixing through the recycle loop allows continuous monitoring of reaction progress. Electrochemical generation of free radicals allows their controlled mediation into the reaction mixture for more efficient reaction. Kinetic profiles provide mechanistic insight into reactions under electrochemical control.

A Compact Reactor-Pump-Cell-Injection System for In-Situ / On-Line Spectroscopic Studies
Compact reaction systems for exploratory studies, over wide pressure intervals, are essential in many applications. This is particularly true for studies involving very expensive reagents and isotopes. The system was used for heterogeneous catalysis, with a chiral fixed bed reactor. The system consisted of a 25ml 2-phase stirred-tank(gas, liquid), liquid phase pump, a fixed bed reactor with sma...
