the presence of a highlyeffective Pd/CM-phos catalyst, cyanation of aryl chlorides proceeds at 70 °C in general, which is the mildest reaction temperature achieved so far for this process. Common functional groups such as keto, aldehyde, ester, nitrile and −NH2, and heterocyclic coupling partners including N−H indoles are well tolerated. Moreover, a sterically hindered nonactivated ortho,ortho-disubstituted
