A unified strategy for the synthesis of 2-vinyl heterocycles is reported. With visible light irradiation, simple and cheap CuCl is able to functionalize a terminal alkyne, giving Cu(I)-acetylide in situ. Unlike the case of noble metals or organic dye photocatalysts, this critical Cu(I)-acetylide not only activates the C-H bond of terminal alkynes but also serves as a photocatalyst to achieve varieties of 2-vinyl heterocycles in good to excellent yields, even for large scale and late-stage functionalization of natural product.

An efficient Fe(acac)3-catalyzed decarboxylative C(sp 2)-C(sp3) coupling reaction via oxidation of C-H bond adjacent to an oxygen atom has been developed successfully, in which cyclic ethers are selectively transformed into the corresponding alkenylation products with good chemical yields and excellent stereoselectivities. The mechanism was studied and the reaction was supposed to proceed through a radical oxidative coupling process.
