In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Optically active complexes of Schiff bases. I. Syntheses and properties of optically active tetradentate Schiff bases, published in 1972, which mentions a compound: 19777-66-3, mainly applied to Schiff base tetradentate stereochem, Recommanded Product: 19777-66-3.
Reproducible syntheses and resolutions of 1,2-diamines were reported. Isomeric Schiff bases were prepared by condensation of 1 mole of (+),(-), or meso-1,2-diamine with 2 moles MeCOCH2COMe, salicylaldehyde or (+)-hydroxymethylenecamphor and identified by NMR and ir spectra. Configurational studies of the Schiff bases were made on the basis of ORD and CD spectra.
Here is a brief introduction to this compound(19777-66-3)Recommanded Product: 19777-66-3, if you want to know about other compounds related to this compound(19777-66-3), you can read my other articles.
