title: In situ Raman monitoring of [2+2] cycloaddition of pyridine substituted olefins induced by visible laser.
abstract: Visible laser induced [2+2] cycloaddition of solid-state pyridine substituted olefins into cyclobutane has been monitored by an in situ Raman technique. The laser power and wavelength can dramatically alter the reaction kinetics, as a prior melting process (heating from laser irradiation) is required for this [2+2] photoreaction.
