Palladium on Carbon-Catalyzed Chemoselective Oxygen Oxidation of Aromatic Acetals

The development of an unprecedented chemoselective transformation has contributed to forming a novel synthetic process for target molecules. Chemoselective oxidation of aromatic acetals has been accomplished using a reusable palladium on carbon catalyst under atmospheric oxygen conditions to form ester derivatives with tolerance of aliphatic acetals and ketals.

OPTICAL DEVICES

The invention relates to optical devices; especially intraocular lens made from high refractive index polymers produced from hydroxyalkyl acrylates and methacrylates containing aromatic groups and carbonyl groups. The invention also relates to the starting monomers, the polymers produced; the application of the same for the manufacture of optical devices and the products derived therefrom.

A convergence of photo-bergman cyclization and intramolecular chain collapse towards polymeric nanoparticles

Employing enediynes as crosslinking precursors, a novel yet efficient strategy, namely photo-triggered Bergman cyclization, was integrated with intramolecular chain collapse to yield polymeric nanoparticles with the size regime below 20 nm. Enediyne motif was designed delicately to possess a high photo-reactivity, with the double bond locked in a methyl benzoate ring while triple bonds substituted with phenyls. Single electron transfer-living radical polymerization was conducted to provide linear acrylate copolymers with controlled molecular weights and narrow polydispersities. Poly(butylarylate-co- 5) went through UV-irradiation with a concurrent Bergman cyclization, resulting in well-defined ultrafine polymeric nanoparticles. Results from NMR, Raman scattering, photoluminescence and UV-vis spectra corroborated the presence of conjugative structures in the polymeric nanoparticles, indicating the occurrence of photo-induced Bergman cyclization. A series of other acrylate-based nanoparticles were investigated to confirm the applicability of such a unique strategy in thermal sensitive but UV-stable polymeric structures, making photo-Bergman cyclization a promising tool towards polymeric nanoparticles.
