✦ Synopsis

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 give hydroxy‐or mono‐ketones.
