Selective nickel- and manganese-catalyzed decarboxylative cross coupling of some α,ß-unsaturated carboxylic acids with cyclic ethers.

A nickel- and manganese-catalyzed decarboxylative cross coupling of α, ß-unsaturated carboxylic acids with cyclic ethers such as tetrahydrofuran and 1, 4-dioxane was developed. Oxyalkylation was achieved when nickel acetate was used as catalyst, while manganese acetate promoted the reaction of alkenylation.
