✦ Synopsis

Aromatic nitriles are readily formed by bis(trifluoroacetates) with CuCN in acetonitrile. heating arylthallium Electrophilic thallation of arenes with thallium tris(trifluoroacetate) (TTFA), followed by replacement of the resulting thallium substituent by other groups, constitutes a flexible procedure for aromatic substitution, often with an unusual degree of orientation control. 3 Two methods, for example,
