Detailed Description
Product name: (1R,2R)-(+)-1,2-Diphenylethylenediamine Alias: (1R,2R)-(+)-1,2-Diphenyl-1,2-ethanediamine; (1R,2R)-(+)-1,2-Diamino-1,2-diphenylethane Structural formula: Molecular formula: C14H16N2 Molecular weight: 212.29 CAS No.: 35132-20-8 Physicochemical property: Melting point: 81-84ºC Boiling Point: 353.9°C at 760 mmHg Flash point: 199.9°C Specific rotation: 104º(C=1.1, MEOH 25ºC) Purity: 95% HPLC Usage: Is important to have a C2-symmetry axis of the chiral reagent. Has been widely used in asymmetric synthesis and optical resolution, such as non-official of the asymmetric epoxidation of olefins, asymmetric aldol condensation reaction, asymmetric Diels-Alder reaction, asymmetric carbonyl allylation, optical activity of allene-based alcohol and propargyl alcohol-based synthesis, with no functional groups asymmetric epoxidation of olefins and binaphthol split and so on.
