Preparation of Some Pyrrole-3,4-dicarboxylic Acid Derivatives and the Crystal Structure of 2-Methylpyrrolopyrrole-1,3(2H,5H)-dione

A series of pyrrole-3,4-dicarboxylic acid derivatives has been prepared, and the crystal structure of one, 2-methylpyrrolopyrrole-1,3(2H,5H)-dione, has been determined by X-ray diffraction and refined to a residual R 0.049 for 1415 observed reflections.Crystals are monoclinic, space group P21/c, with Z = 8 in a cell of dimensions a 14.775(3), b 7.0692(5), c 15.151(3) Angstroem, β 118.82(8) deg.Strain in the planar fused ring system is evident from the widening of the external interring angles to 143 deg, and from the unusual substituent effects in the 13C n.m.r. spectra.
