Abstrakt: Polarization and steric effects of the alkylhetero groups have the main influence on the C chemical shifts of the vinyl fragment in alkyl vinyl sulfoxides and sulfones. In sulfones, an appreciable role can be played by a π-acceptor interaction between the sulfur atom and the double bond. [ABSTRACT FROM AUTHOR]
