Synthesis and Characterization of Novel Dialdehydes based on SN2 Reaction of Aromatic Aldehyde

Author(s): Ali Alasmi and Joumaa Merza

Four new dialdehydes compound (I, II, III, IV) containing oxygen donor atoms have been synthesized in good yields (about 80%) from the condensation reactions of Salicylaldehyde with dibromoethane and bis(2-chloroethyl) ether, And from the condensation reactions of Vanillin with di-bromoethane and bis(2-chloroethyl)ether], respectively. The reaction followed by using thin layer chromatography (T.L.C). Four series of dialdehydes, namely 2,2'-(ethane-1,2-diylbis(oxy)) dibenzaldehyde(I), 2,2'-((oxybis(ethane-2,1-diyl)) bis(oxy)) dibenzaldehyde (II), 4,4'-(ethane-1,2-diylbis (oxy))bis (3-methoxybenzaldehyde)(III), 4,4'-((oxybis (ethane-2,1-diyl))bis(oxy)) bis(3-methoxybenzaldehyde)(IV) were characterized by elemental analyses, FT-IR, UV-Vis, HPLC, 1H,13C-NMR
