Synthesis and structure oftrans-1,2,3-
tris(3-thenoyl)cyclopropane / Saba, Antonio. - In: ACTA CRYSTALLOGRAPHICA. SECTION C, CRYSTAL STRUCTURE COMMUNICATIONS. - ISSN 0108-2701. - 50:(1994), pp. 271-274. [10.1107/S0108270193008820]
Abstract:
The title cyclopropane derivative, C18H12O3S3, was synthesized
and its structure investigated by single-crystal
X-ray diffraction and spectroscopic methods. This structure
analysis addresses the problem of spontaneously resolved
helical stereoisomerism. The temperature-dependent1H NMR spectrum shows a relevant barrier to rotation
about the CO-thiophene bonds, with ∆G423-~
89 (21) kJ mo1-1.
