Photochemical reactor sensitized oxidations

Trifluoronitrosomethane (b.p. 86.0°C, 767 mm Hg) is of considerable interest as a component of high temperature-resistant elastomers. This compound has been prepared by treatment of trifluoroiodomethane, in the presence of mercury, with nitric oxide in a photochemical reactor whose mercury lamp emitted radiation at 253.7 mp.. The preparation is particularly sensitive to the initial pressure of the gases, reactant ratio, irradiation time, intensity of the ultraviolet radiation, reaction temperature, and method of removal of nitric oxide from the product [60]. 

Another singlet oxygen photochemical oxygenation of a-terpinene was performed in a microstructured reactor [136]. A solid supported [60] fiillerene photosensitizer that was grafted to Tentage beads was used as singlet oxygen sensitizer. Oxidation of a-terpinene was achieved within 50 s.
