Catalytic amount of Cobalt(II) chloride in 1,2-dichloroethane promotes the allylation of 1,3-dicarbonyl compounds with allyl acetates in high yields. The allylation of pentane-2,4-dione is highly regioselective as compared with methylacetoacetate and ethyl 2-oxocyclopentanecarboxylate.
shows extraordinary high activity in the decarboxylative coupling of cinnamic acids with alcohols. In addition, the Cu-X catalyst presents excellent performance in the oxidativecoupling of alkenes with aldehydes. The strong interaction between Cu+ and the zeolite framework benefits the transformation of Cu2+ and Cu+ in the redox process, enhancing the reaction activity. More importantly, the Lewis basic
