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
