Dibenzylaniline or N,N-Dibenzylaniline is a chemical compound consisting of aniline with two benzyl groups as substituents on the nitrogen.
The substance crystallizes in the monoclinic crystal system. The space group is P21/n. The unit cell dimensions are a=11.751 Å b=9.060 Å c=29.522 Å, and β=94.589°.[1] Each unit cell contains two molecules. In the solid van der Waals forces hold it together.[2] The substance can also crystallize in alternate monoclinic form.[3]
Production
One method to produce dibenzylaniline is using a mixture of dibutyl tin dichloride and dibutyl stannane with N-benzilideneaniline along with hexamethylphosphoric triamide dissolved in tetrahydrofuran which yields a tin amide compound. This then reacts with benzyl bromide to yield dibenzylaniline.[4]
Another method uses aniline and benzyl bromide.
Use
It used to make dyes.
A nitroso derivative (made using nitrite and hydroxylamine) can be used in a colourimetric test for palladium.[5]
