Reactions of alkenes with di-n-propyl, diphenyl, and dibenzyl disulphide in the presence of lead(IV) salts in trifluoroacetic acid-dichloromethane are described. The products, vicinal trifluoroacetoxy-sulphides, are obtained in higher yields with manganese (III) salts as the oxidant. Alternative reaction conditions with use of iron(III) salts or in the absence of added metal salts are also described
Phenylsulphenamides react chemoselectively with an alkene and a nitrile in the presence of trifluoromethanesulphonic acid to give -(β-phenylthioalkyl) amidines; in the absence of nitrile an amine is formed.
