Xylenes is a mixture of isomeric ortho-,meta- and para- forms of xylene which is an aromatic hydrocarbon widelyused as a solvent in various chemical reactions.

Application

Xylenes can be used as a solvent:

In the tetraphosphine/palladium-catalyzed Suzuki cross-coupling with sterically hindered aryl halides and arylboronic acids to synthesize tri-ortho-substituted biaryl adducts.
For the N-alkylation of amines or ammonia with alcohols to synthesize N-alkyl amines.
To synthesize aromatic polyimides by reacting unsymmetric phosphinated diamines and dianhydrides via solution polymerization.
