Synthesis and Characterization of Some New Tetraaldehyde and Tetraketone Derivatives and X-Ray Structure of 1,1′-(4,4′-(2-(1,3-Bis(4-Acetylphenoxy)propan-2-ylidene)propane-1,3-di-yl)bis(oxy)bis(4,1-phenylene))diethanone

Abstract

Tetraketone and tetraaldehyde derivatives 2a-d were synthesized via the reaction of ethene-1,1,2,2,-tetra-yl-tetramethylene tetrabromide (1) with hydroxyketone and aldehyde derivatives. The molecular structures were identifed by IR, 1H-NMR, 13C-NMR and MS analysis. The crystal structure of the title compound 2a, C <inf>38</inf>H <inf>36</inf>O <inf>8</inf>, is reported. Its crystal data are: monoclinic, space group P 2(1)/n with cell dimensions of a= 9.0395(12) Å ,b= 12.6114(17) Å, c = 13.8166(18) Å, β= 95.875(3), V= 1566.8(4) Å 3, F.W.= 620.67, ρ <inf>calc</inf> =1.316 gcm 3 for Z=2, μ=0.092 mm -1. © 2008 by the authors; licensee Molecular Diversity Preservation International.
