1,2-Dianilinoethane Usage And Synthesis

Chemical Properties

BEIGE TO LIGHT BROWN CRYSTALLINE POWDER

Uses

1,2-Dianilinoethane can forms crystalline imidazolidines with aldehydes in the presence of AcOH. N-donating ligand. Can be used as a trapping agent for aldehydes.

Application

N,N′-Diphenylethylenediamine can be used:
To prepare nickel(II) chelates to study their chemical reactivities.
To prepare N-heterocyclic carbene (NHC) adducts by reacting with substituted benzaldehydes.
As a starting material to prepare substituted cyclic poly(methyl methacrylate)s.
