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.

Cephalopods can display dazzling patterns of colours by selectively contracting muscles to reversibly activate chromatophores--pigment-containing cells under their skins. Inspired by this novel colouring strategy found in nature, we design an electro-mechano-chemically responsive elastomer system that can exhibit a wide
