Reactions of arensulfenamides with olefins in the presence of picric acid
N-(2-and 4-Nitrophenylthio)morpholines in the presence of equimolar amounts of picric acid enter into the reaction of electrophilic sulfenylation of the C=C norbornene bond to give bi-and tricyclic sulfides. With cyclohexene, trans-2-arylthiocyclohexanol are formed.
A number of crystalline, hydrogen-bonded complexes of ureas and phenols are reported.The most commonly observed urea-phenol ratio is 1:1, but some complexes with ratios of 2:1, 1:2 and 1:3 were encountered.The structures of these complexes are discussed and one degradative reaction is described.
