The Pd-catalyzed addition of carbon monoxide and carbon tetrachloride to 1-octene gave coadduct [alkyl 2-(2,2,2-trichloroethyl)octanoate] as the major product in supercritical carbon dioxide by using pyridine as the b...The Pd-catalyzed addition of carbon monoxide and carbon tetrachloride to 1-octene gave coadduct [alkyl 2-(2,2,2-trichloroethyl)octanoate] as the major product in supercritical carbon dioxide by using pyridine as the base. It was found that the selectivity and the yield of coadduct were greatly affected by the pressure of carbon dioxide,the reaction temperature and the amounts of alcohol and base used.展开更多
