SYNTHESIS AND PROTOTROPIC ISOMERIZATION OF 1-NITROPHENYL-2-ACYLPYRROLES
Pina, M.C.,Budilin, V.A.,Rodrigues, M.,Bundel, Yu. G.
, p. 268 - 271 (1989)
Acylation of 1-nitrophenylpyrroles by acid anhydrides leads to 2-acylpyrroles or their mixtures with 3-acylpyrroles, the formation of the latter being explained by acid isomerization of the 2-isomers.
