General description
1,2-Dichloropropane, also known as Propylene dichloride, is a chlorinated solvent, that is commonly utilized as an intermediate in the synthesis of basic organic chemicals.
Application
1,2-Dichloropropane can be used as a building block to synthesize:
- 2-Ylidene-1,3-dithiolane derivatives via one-pot reaction with carbon disulfide and active methylene compounds in the presence of sodium ethylate.
- β-Chloropropylsulfurs by controllable dechloro-coupling reaction with thiols.
- Thiazolidine and 1,3-thiazinane derivatives via [3+2] and [3+3] annulation reaction with β-ketothioamides in the presence of phosphonium ylide as a catalyst.
