2,6-Diisopropylaniline is a liquid aromatic amine with the formula H 2 NC 6 H 3 (CH (CH 3 ) 2 ) 2 . It is a colorless liquid, but like many other aniline derivatives , samples can appear yellow or brown.
use
Due to its high steric demand , 2,6-diisopropylaniline is used for the synthesis of ligands in coordination chemistry . Many transition metal complexes based on Schrock carbene carry imido ligands derived from this aniline. The condensation with 2,6-diacetylpyridine leads to diiminopyridine ligands , that with acetylacetone to NacNac ligands .
In some carbenes, too, the sterically demanding diisopropylphenyl substituents are introduced by 2,6-diisopropylaniline.
