| مستخلص: | The oxidative coupling polymerization of the novel quaternaphthyl monomers, such as (S,S,S)-3,3”’-dihydroxy-2,2’,3’,2”,3”2”’-hexamethoxy-1,1’:4’,1”:4”,1”’-quarter-naphthyl and (S,S,S)-3’,2”-dibenzyloxy-3,3”’-dihydroxy-2,2’,3”2”’-tetramethoxy-1,1’:4’,1”:4”,1”’-quaternaphthyl, with the copper(I) chloride-(S)-2,2’-isopropyridene-bis(4-phenyl-2-oxazoline) catalyst was performed. The obtained polybinaphthol derivatives consisted of about 20 repeating naphthalene units and the stereochemical composition of up to an 88% enantiomer excess (S). [ABSTRACT FROM AUTHOR] |
