Abstract
1 H and 13C n.m.r. spectroscopy at low temperature allowed the detection of restricted rotation about the N–N bond in sulphinylhydrazines. In the case of the di-isopropyl derivative the existence of two conformers due to a ‘correlated orientation’(gear effect) was also discovered. The trend of the measured ΔG‡ values and the interpretation of the chemical shifts suggested conformational assignments which were supported by an X-ray diffraction investigation of the solid.Keywords
