The reaction of aromatic nitroso-compounds with enamines. Part I. The reaction of nitrosobenzene with 1-morpholin-1-ylcyclohexene

The reaction of nitrosobenzene with 1-morpholin-1-ylcyclohexene gives the hydroxylamine (1; R = H) as the initial product. On standing (1; R = H) rearranges into N-(2-hydroxy-2-morpholin-1-ylcyclohexylidene)aniline (2). The reactions of (1; R = H) and (2) are discussed.
