basic hydrolysis yields the ring expansion product cyclichydroxamicacids in 12–81% yield. Reactions of substituted cyclopentanones provide ring expanded products where the –NOH group regioselectively inserts to the more substituted position and gives a better yield compared to the treatment of the same ketone with a basic solution of Piloty’s acid. Reaction of phosphines with acyloxy nitroso compounds

An atom‐economic intermolecular radical addition reaction of acyloxy nitroso compounds to electron‐deficient alkenes mediated by visible light is reported. The starting nitroso derivatives are readily prepared by oxidation of the corresponding oximes prepared from ketones and the overall transformation represents an oxidative coupling of a ketone with a Michael acceptor. The cascade proceeds smoothly

complexes inhibit nitrous oxide formation. Hydrolysis of these compounds in the presence of ferric heme complexes forms ferrous nitrosylcomplexes providing further evidence for the intermediacy of HNO. Kinetic analysis shows that the rate of hydrolysis depends on pH and the structure of the acyl group of the acyloxy nitroso compound. These compounds relax pre-constricted rat aortic rings similar to known
