2-tert-Butylaniline is a sterically hindered aniline. 2-tert-Butylaniline participates in chemo- and regioselective copper-catalyzed cross-coupling reaction for the effective amination of 2-chlorobenzoic acids.2-tert-Butylaniline may be used in the preparation of 2,3-bis(2-tert-butyl-phenyl-imino)butane.It may be used in the preparation of two rotamers, anti- and syn-N,N′-bis-(2-tert-butylphenyl)naphthalene-1,4,5,8-tetracarboxylic diimides and their guest inclusion abilities were investigated
