In an article, published in an article, once mentioned the application of 4488-22-6, Name is [1,1′-Binaphthalene]-2,2′-diamine,molecular formula is C20H16N2, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C20H16N2
The title compound 3 has been prepared via a highly selective, Cu(II)-mediated cross-coupling of 2-aminonaphthalene 1 and 2-naphthol 2 and resolved into enantiomers via crystallization of diastereoisomeric salts with (1S)-(+)-10-camphorsulfonic acid. The method has been optimized and the use of chromatography eliminated.
