title: 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 identified by IR, (1)H-NMR, (13)C-NMR and MS analysis. The crystal structure of the title compound 2a, C(38)H(36)O(8), is reported. Its crystal data are: monoclinic, space group P 2(1)/n with cell dimensions of a=9.0395(12) A, b=12.6114(17) A, c=13.8166(18) A, beta=95.875(3), V=1566.8(4) A(3), F.W.=620.67, rho(calc)=1.316 gcm(3) for Z=2, mu=0.092 mm(-1).
