An iridium(I) catalyst system, modified with the wide-bite-angle and electron-deficient bisphosphine dFppb (1,4-bis(di(pentafluorophenyl)phosphino)butane) promotes highly branch-selective hydroarylation reactions between diverse acetanilides and aryl- or alkyl-substituted alkenes. This provides direct and ortho-selective access to synthetically challenging anilines, and addresses long-standing issues associated with related Friedel-Crafts alkylations.

The nitration of benzothienobenzothiophene with concentrated nitric acid in acetic acid leads to the formation of 2-nitro- and 4-nitrobenzothienobenzothiophene, from which the corresponding amines were obtained.
