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-diyl)bis(oxy)bis(4,1-phenylene))diethanone
Özet
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, H-1-NMR, C-13-NMR and MS analysis. The crystal structure of the title compound 2a, C38H36O8, is reported. Its crystal data are: monoclinic, space group P 2 (1)/n with cell dimensions of a= 9.0395(12) angstrom, b= 12.6114(17) angstrom, c = 13.8166(18) angstrom, beta= 95.875(3), V= 1566.8(4) angstrom(3), F. W.= 620.67, rho(calc) =1.316 gcm(3) for Z=2, mu=0.092 mm(-1).
