The differently substituted 2,5-diarylthiazole derivatives are synthesized via palladium catalyzed sequential C-H arylation at the 5-position and C-C bond activation at the 2-positon with masked thiazole.

Silica nanotubes (SNTs) functionalized with Pd-NPs on the inner surface performed as efficient nano-reactors for CâC coupling in water; the nano-confinement offers minimized leaching of Pd and yet efficient mass transfer for SuzukiâMiyaura coupling and CâH arylation of thiazoles in water with very high TON.
