Deskripsi
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, 13CNMR 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) Å ,b= 12.6114(17) Å, c = 13.8166(18) Å, β= 95.875(3), V= 1566.8(4) Å3, F.W.= 620.67, ÃÂcalc =1.316 gcm3 for Z=2, μ=0.092 mm-1
