Pd salts catalyseoxidation of alcohols with CCl4 in the presence of K2CO3. Primary alcohols are oxidised to esters, and secondaryalcohols to ketones. CCl4 is converted to CHCl3. The reaction of allylicalcohols bearing a terminal olefinic bond with CCl4 or BrCCl3 in the presence of palladium catalyst at 110° affords 4,4,4-trichloro ketones. At 40°, simple adducts of CCl4 or BrCCl3 having a halohydrin
