arenes and heteroarenes into the ortho-cyano derivatives was achieved through directed lithiation followed by electrophiliccyanation with phenyl cyanate. This reaction method proved to be applicable to halogen–lithium exchanged intermediates, so especially useful for the synthesis of benzonitriles. The scope of the reaction sequence was explored using a number of substrates.
