Application of 499-40-1. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal. In a document type is Article, introducing its new discovery.
Reactions of (M = Mo or W; bipy = 2,2′-bipyridyl) with di-2-pyridylamine,(C5H4N)2NH (dipyam), yield the isostructural mixed-ligand complexes .Both complexes crystallise in the monoclinic space group P21/c with, Mo, a = 10.620(15) <10.564(6)>, b = 12.915(12) <12.925(6)>, c = 16.524(26) <16.508(12)> Angstroem, beta = 107.81(11) <107.83(6)> deg, and Z = 4.The complexes have fac-octahedral structures with bidentate 2,2′-bipyridyl and monodentate di-2-pyridylamine ligands.Substitution of monodentate heterocyclic amines, L, in (M = Cr, Mo, or W) yields the mixed-ligand complexes which have three well resolved upsilon(CO) stretching absorptions in their i.r. spectra.This contrasts with the two upsilon(CO) bands characteristically observed in the analogous fac- or fac- (phen = 1,10-phenanthroline) complexes and raises the possibility that the complexes may have the relatively unusual mer-octahedral geometry.Binuclear di-2-pyridylamine-bridged complexes are readily obtained from the reactions of with di-2-pyridylamine.
