General description

Sodium hydrosulfide hydrate is a hydrated inorganic salt of sodium. It participates in the synthesis of (E)-2-cyano-2-(thiazolidin-2-ylidene)ethanethioamide.

Application

It may be used as a sulfur nucleophile to induce the C-S bond formation in α,β-dichloro vinyl ketones to form 5- to 8-membered cyclic thioethers.
Sodium hydrosulfide hydrate may be used in the synthesis of following:
  • benzothiazole
  • 4-methoxybenzothioamide
  • 2-(4-methoxyphenyl)imidazoline
  • 7-chloro-4′-methoxythioflavone
