Photochemistry of ((Trifluoromethyl)azo)cyclopropane: A Reinvestigation

Article abstract of DOI:10.1021/jo00292a024

The solution-phase photolysis of ((trifluoromethyl)azo)cyclopropane (TFMACP) leads to a very different product distribution than the one reported previously.While CF3H was claimed to be the major product, we instead find much cis-TFMACP, 1-(trifluoromethyl)-2-pyrazoline (5), and (trifluoromethyl)cyclopropane.The four primary photoreactions responsible for these products are exactly analogous to those taking place in azocyclopropane.
