CATALYTIC DEHALOGENATION OF ORGANIC HALID ES IN 2-PROPANOL WITH PD C CATALYST/

Catalytic dehalogenation of organic halides was carried out in a 2-pro panol solution of NaOH with Pd/C at temperatures below 82 degrees C. I t was found that the aliphatic halides were converted to the correspon ding halogen-free hydrocarbons with high yields, although the reaction rate was much slower than that of aromatic halides. Among the substra tes containing I, Br and Cl, the order of dehalogenation rate was I > Br > Cl. The halogen at the terminal position of the carbon chain was easily dehalogenated rather than the internal halogen.
