A new three-dimensional cycloaddition compound and its inclusion complexes formed by 1,3-dipolar cycloaddition reaction of p-phenylenebis(3-sydnone) and N-phenylmaleimide
摘要:
A new three-dimensional heterocyclic compound was synthesized from p-phenylenebis(3-sydnone) and N-phenylmaleimide. This compound incorporates solvent molecules into the crystal lattice to form new inclusion complexes. The structure and the desolvation process were examined by the use of X-ray diffraction, thermogravimetry, differential thermal analysis, FT-IR spectra, H-1 NMR spectra, and solid-state high-resolution C-13 NMR spectra. The host compound may possibly be one of the precursory materials of novel ladder polymers.
