A Simple, Readily Accessible, and Effective Apparatus for the ­Photoisomerization of cis-Cyclooctenes to trans-Cyclooctenes

Abstract A simple, cost effective, and readily accessible apparatus for the photoisomerization of cis-cyclooctenes to trans-cyclooctenes is described. Utilizing only FEP tubing, aluminum vent pipe, a household germicidal lamp, and a flash chromatography system, trans-cyclooctenes can be prepared in good yield.
