1-Trifluoromethyl-2-chloroethylthiolated carbonyl compounds: Synthesis and properties

1-Trifluoromethyl-2-chloroethylsulfenyl chloride thiolates enolizible ketones, forming products of mono- and disubstitution. The properties of the resultant sulfides are determined by the presence in the molecule of two acidic CH centers. Thus, bromination proceeds at the ambident center and reaction with bases leads to (1-trifluoromethylvinyl) sulfides which are able to undergo intramolecular cyclizations and Diels-Alder reactions.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 676–681, March, 1991.
