2.03.7.2.5 By reaction with sodium sulfide. Sodium sulfide, often used as its hydrate, can react with dihalides to yield a cyclic disulfide such as a dithiolane, or with monohalides to give a symmetrical disulfide. Examples of the cyclization reaction are well illustrated by synthetic approaches to both racemic and optically pure lipoic acid ...
