A silver catalyzed decarboxylative C(sp2)–C(sp3) coupling of vinylic carboxylic acids with alcohols, alkylbenzenes, cycloalkanes and cyclic ethers was developed by using DTBP as an oxidant. This reaction tolerates a wide range of substrates, and products are obtained in good to excellent yields. The reaction also shows good stereoselectivity, and only trans-isomers are obtained. In addition, a radical

ligand-unsupported Ag···Ag interactions (3.218(4) A), while a pair of symmetry-related silver(I) atoms in 2 are clamped by two μ2-η1:η1 4-chlorocinnamate ligands to yield a binuclear silver(I) moiety incorporating a ligand-supported Ag···Ag interaction (2.819(5) A). Both complexes 1 and 2 show potent urease inhibitory activities with the respective IC50 values of 0.66 and 1.10 μM.
