2,5-DI-TERT-BUTYLANILINE

2,5-Di-tert-butylaniline has been used in the preparation of:

• new rigid bidentate nitrogen ligands 1,2-bis[(2,5-di-tert-butylphenyl)imino]acenaphthene (dtb-BIAN)
• N-(2,5-di-tert-butylphenyl)perylene-3,4-dicarboximide

The aniline recrystallises from EtOH in fine needles after steam distillation. It has a pKa2 5 of 3.58 (50% aqueous EtOH). The tosylate has m 164o (from AcOH).
