Volume : II, Issue : VIII, September - 2012 Synthesis Of Schiff's Base Ligands By Condensation Of 2-hydroxyacetophenone And Chiral Diamines Manoj Kumar Agrawala , Manish Kaushik , Amit Singhalc Published By : Laxmi Book Publication Abstract : Three optically active Schiff-base ligands 2-4 have been prepared by thermal
condensation of 2-hydroxyacetophenone 1 with (1R,2R)-(-)-1,2-diaminocyclohexane,
(1S,2S)-(-)- 1,2-diphenylethylenediamine or R-(+)-2,2'-diamino-1,1'-binaphthalene,
respectively. The products have been characterized by their elemental analysis, IR, 1HNMR
spectra. Keywords : Article : Cite This Article : Manoj Kumar Agrawala , Manish Kaushik , Amit Singhalc, (2012).
