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.

Studies on oxidation of tert-butyl ethers in the presence of chloride ions proved that acid medium favoured formation of chloro organic compounds. 1,2-Dichloro-2-methylpropane, 3-chloro-2-chloromethylpropene were identified among the reaction products. Presence of these compounds was identified both in the case
