The Pseudo-Gomberg Reaction of Benzene Derivatives with 1-Substituted Pyrroles

抄録

The pseudo-Gomberg reaction of 1-substituted pyrrole derivatives with substituted anilines was examined. Pyrrole derivatives with electron-attracting groups at the 1-position, i.e., ethoxycarbonyl, methanesulfonyl, and benzoyl groups, were found to react smoothly with nitroaniline, chloroaniline and aniline. In each case, 2-arylated pyrrole derivatives were obtained in good or moderate yields.
