REACTIONS OF ACETYLENIC GAMMA-GLYCOLS .31. DIPHENYLMETHYLENECHLOROCYCLOSULPHONES AND THEIR SPECTRAL AND STRUCTURAL-PROPERTIES

Influence of substituents in asymmetric diols on formation of chlorocy closulphones in direct reaction with SOCl2 and on isolated intermediat e - chlorohydroxyallenes - was investigated. Some structural parameter s of chlorocyclosulphones were obtained by the NMR (H-1 and C-13), IR, UV/Vis and X-ray analysis. In UV/Vis spectra the small solvent effect was measured and changes in coupling system caused by substituent R ( alkyl or phenyl in position 4) or by state (solid and in solvents) wer e observed. Long range coupling constants for compound 10 were found. It was shown, that formation of intermolecular hydrogen bonds between SO2 and CH2 groups is possible for compound 12 in solid state.
