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.
通过原位拉曼技术监测到固态吡啶取代烯烃的可见激光诱导[2+2]环加成反应生成环丁烷。激光功率和波长可以显著改变反应动力学，因为这种[2+2]光反应需要先进行熔融过程（激光照射加热）。
