Pulsed Nd:YAG laser-induced photoreaction of cis,cis-1,3-cyclooctadiene at 266 nm: selective cyclization to cis-bicyclo[4.2.0]oct-7-ene†
Abstract
Nanosecond-scale pulsed laser irradiation of cis,cis-1,3-cyclooctadiene via an Nd:YAG laser at 266 nm induced highly selective cyclization of the 1,3-diene moiety to afford cis-bicyclo[4.2.0]oct-7-ene in high yield. The pulsed Nd:YAG laser light is highly monochromatic thereby allowing efficient control of the photoreaction selectivity by controlling the photostationary state.
