block copolymers while preparing hydrophobic blocks by polymerizing the monomer solution in the presence of a mixed catalyst of cesium carbonate catalyst, or cesium carbonate and alkaline-earth metal carbonate, or a mixed catalyst of cesium carbonate and alkaline-earth metal carbonate.;COPYRIGHT KIPO ...
The present invention concerns a novel method for preparing polymers (preferably (meth)acrylate polymers and copolymers) having a narrow molecular weight distribution by metal-free anionic polymerization in the presence of a phosphonium cation. The present invention also concerns block copolymers and metho...
3.2. Synthesis of Compounds 2a and 2b 4-Nitro-1H-indazole (1) (820 mg, 5.02 mmol) was dissolved in anhydrous DMF (10 mL), cesium carbonate (1.798 g, 5.52 mmol) and 4-methoxybenzyl chloride (864 mg, 5.52 mmol) were added at ambient temperature. The resulting mixture was allowed to ...
Compound 4 was obtained by reacting Compound 3 with TyEDTA-tert-butyl ester and cesium carbonate in anhydrous THF under reflux conditions. Compound 5 was synthesized by reacting Compound 2 with Compound 4, TBTA, and sodium ascorbate in methanol. This step involved the deprotection of tert-butyl ...
