## Abstract The kinetics of the base‐catalysed H/D exchange of the 1‐methylthiolanium cation in heavy water has been studied. Of the four α‐methylene protons, two exchange much faster than the other two, a result which requires that reprotonation of the carbanion intermediate occurs with retention

## Abstract Monoketones react with hydrogen sulfide in the presence of basic catalysts to give geminal dithiols or thioketones. β‐Diketones are converted into monothiodiketones. α‐Diketones can be selectively reduced by hydrogen sulfide in the cold in the presence of secondary or tertiary amines to
