CLEAVAGE OF CARBON–HALOGEN BOND BY THE HYDROGEN TRANSFER FROM ORGANIC COMPOUNDS CATALYZED BY NOBLE METAL SALTS
In the presence of noble metal salts, especially Pd(II) salts, the carbon–halogen bond of aryl halides underwent hydrogenolysis with organic hydrogen donors such as indoline and tetrahydroquinoline, and the corresponding aryl compounds and hydrogen halides were formed. The addition of bases promoted the hydrogenolysis.
