XYLENES ACS REAGENT >=98.5% XYLENES + ETHYLBENZENE BASIS (C005B-015197)

General description

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.
