Photochemical Reactions as Key Steps in Organic Synthesis

Photochemical Reactions as a Tool in Organic ..

Photochemical reactions are generally easily carried out, at least in laboratory scale, and require no expensive apparatus. Some general reactions, e.g. the cycloaddition of enones to alkenes and various oxygenations have been extensively investigated and represent an excellent choice for preparative applications. Many other possibilities are known—and a few are presented below. This suggests that photochemical steps should be considered more often in synthetic planning.

In addition, however, photochemical reactions ..

In nature, there are a number of light excited photochemical reactions such as , or photo degradation etc. Special herbal substances react only by exposure to light and thus develop their phototoxic potential.

Photochemical reactions in organic synthesis: A novel …

Green chemistry has become a central issue in present-day chemistry. Photochemical reactions appear to have a great potential because in-depth chemical transformations are obtained in the absence of chemical activators, and thus no waste is produced. However, the actual “green” character of purported environmental-friendly reactions must be checked by an appropriate metrics at least when artificial lamps are used, in order to evaluate the energy consumption. Most photochemical processes are reported at a very low scale in the literature, and often at a low concentration. The scaling up issue is briefly discussed. On the other hand, another green function of photochemistry is degradative photocatalysis for the degradation of pollutants, one of the most efficient advanced oxidation methods available.
