So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Habaue, Shigeki; Seko, Tomoaki; Okamoto, Yoshio researched the compound: Bis((S)-4-phenyl-4,5-dihydrooxazol-2-yl)methane( cas:132098-59-0 ).Computed Properties of C19H18N2O2.They published the article 《Copper(I)-Catalyzed Asymmetric Oxidative Coupling Polymerization of 2,3-Dihydroxynaphthalene Using Bisoxazoline Ligands》 about this compound( cas:132098-59-0 ) in Macromolecules. Keywords: copper bisoxazoline complex polymerization catalyst oxidative coupling; polydihydroxynaphthylene preparation chain structure copper bisoxazoline catalyst. We’ll tell you more about this compound (cas:132098-59-0).
The asym. oxidative coupling polymerization of 2,3-dihydroxynaphthalene with complexes of Cu(I)-bisoxazoline as catalysts under an O2 atmosphere was carried out to produce poly(2,3-dihydroxy-1,4-naphthylene) having a continuous 1,1′-bi-2-naphthol main chain structure. The polymerization with (S)-2,2′-isopropylidenebis(4-phenyl-2-oxazoline) as catalyst ligand at room temperature for 24 h afforded a methanol-insoluble polymer in 30% yield with a mol. weight of approx. 4.1 × 103 as estimated by 13C NMR data; the polymer was quant. obtained after 48 h. The obtained polymer was rich in the S-configuration. The structure of the bisoxazoline ligand significantly affected the catalyst activity and stereoselectivity.
Although many compounds look similar to this compound(132098-59-0)Computed Properties of C19H18N2O2, numerous studies have shown that this compound(SMILES:C1(CC2=N[C@@H](C3=CC=CC=C3)CO2)=N[C@@H](C4=CC=CC=C4)CO1), has unique advantages.
