Hawkins, Joel M.; Meyer, Axel; Nambu, Mitch published the artcile< Asymmetric bisosmylation of fullerene C60: novel chiral π-systems>, HPLC of Formula: 112-63-0, the main research area is stereoselective regioselective bisosmylation fullerene; fullerene osmium complex chiral; cinchona alkaloid stereoselective biosmylation fullerene.
Two isomers of C60(OsO4py2)2 are chiral by virtue of the substitution pattern on the icosahedral carbon cluster. Treatment of C60 with two equiv of OsO4 and five equiv of cinchona alkaloid derivative, followed by exchange of the chiral ligands for pyridine, gives the chiral (C2) isomers of C60(OsO4py2)2 with optical rotations up to 3700° and CD spectra which reflect the novel chiral band-shaped π-systems of these compounds The regiochem. and stereochem. of the bisosmylation of C60 appear to be controlled by attractive electronic interactions between the arene components of the cinchona alkaloid ligands and the fullerene surface.
Journal of the American Chemical Society published new progress about Dihydroxylation, stereoselective. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.
