TCI B6606 is a sterically demanding N,N'-diaryl benzene-1,2-diamine bearing biphenyl-2-yl and 2-phenylnaphthalen-1-yl substituents. Such o-phenylenediamine frameworks are commonly used as precursors to benzimidazolium salts and N-heterocyclic carbene ligands for organometallic catalysis. The bulky aryl groups create a well-defined steric pocket that can influence catalytic selectivity, and the scaffold is also of interest in functional organic materials. AMI Scientific offers this TCI building block in 250 mg and 1 g pack sizes for catalysis and materials research laboratories.
Advantages (TCI brochure)
- C(sp2)-N cross coupling
- Effective for aryl bromides, primary amines and secondary amines (both cyclic and acyclic) with relatively small steric hindrance
