摘要

The positions of base-catalyzed equilibrium between the a,@- and@, y-unsaturated isomers of alkenyl methyl sulfides, sulfoxides, and sulfones,(eq. 2, X=-SCHa,-SOCH3, and-SOsCH3) have been determined In the compounds containing an alkyl group attached'to the y-carbon atom, the ratios of@, y-to a,@-unsaturated isomers are: in sulfides (X=-SCH3), 34: 66; in, sulfoxides (X=-SOCH,), 96: 4; in sulfones (X=-SOCHI),> 99: 1. In the allyl-propenyl ...
