Ts. Cameron et al., Synthesis and characterization of the heteroaromatic MF6- (M = As, Sb) salts of the 1,2,4-trithiolanylium dication [PhCSSC(Ph)S](2+), CHEM COMMUN, (15), 2001, pp. 1370-1371
PhCSSC(Ph)S(MF6)(2) (M = As, Sb), (X-ray crystal structure, FT Raman, H-1,
C-13 NMR and theoretical calculations) containing the first example of a di
cationic 6 pi five-membered C-S heterocycle and sulfur were formed on dispr
oportionation of PhCSSS(MF6) in liquid SO2 solution.
