Abstract
The cover picture shows the image of the original crystals of the Wheland–Meisenheimer complex between 2,4-dipyrrolidin-1-yl-1,3-thiazole and 4,6-dinitrobenzofuroxan (DNBF) visible under an Olympus SZX10 microscope and photographed by us. X-ray diffraction analysis of zwitterionic Wheland–Meisenheimer complexes [derived from the reaction between 2,4-dipyrrolidin-1-yl-1,3-thiazole and DNBF or 4,6-dinitrotetrazolopyridine (DNTP)] has been achieved for the first time. Details are discussed in the article by L. Forlani, C. Boga et al. on p. 1123 ff. The authors thank Dr. Anna Nasci who created the background and inserted the images of the crystals in a frame of aesthetic appeal.
