, p. 967 - 974 (1997)
Novel styryl dyes containing dithia-15(18)-crown-6(5)-ether moieties were synthesized. Their selective complex formation with Hg2+ and Ag+ ions was studied by 1H NMR and electronic spectroscopy; the stability constants of the Ag+ complexes and the relative stability constants (in relation to benzodithia-18-crown-6) of the Hg2+ complexes were determined. The chemical shifts of the β,β′-protons in the CH2S group change upon the complex formation in parallel with the logK1 values of the complexes.

, p. 109 - 120 (2007/10/02)
The various types of gas/solid-reactions (addition, elimination, substitution, condensation, catalyzed cycloaddition) in different branches of sulfur chemistry (heterocycles, S-vinyl-compounds, thioethers, thiols, sulfur dioxide) are reviewed, new types a
