醋酸

By following the "self-assisted molecular editing" protocol first established in our labs,a number of Aphos ligands were efficiently prepared from a single starting material and they were screened for catalytic efficacy, leading to the discovery of the best-performing Aphos appended with a 3-nitrophenyl group at the C4 position.Combination of this Aphos with Pd_2 offers a precatalyst for successful cross-coupling of unactivated aryl chlorides with aryl boronic acids at room temperature.The reactions took place under mild basic conditions to produce the products in high yields.
