I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 538-58-9, help many people in the next few years.name: 1,5-Diphenylpenta-1,4-dien-3-one
In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: 1,5-Diphenylpenta-1,4-dien-3-one, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. In an article£¬Which mentioned a new discovery about 538-58-9
Formation and X-ray structure of the mu-alkylidene complex Fe2(CO)6(mu-eta3, eta3-C(CH=CHPh)2) upon deoxygenation of Fe2(CO)8(mu-eta2, eta2-C(O) (CH=CHPh)2) with methyl lithium
Di-iron nonacarbonyl reacts with dibenzylideneacetone (5) to produce, depending on the reaction conditions, either a mixture of the three complexes Fe(CO4 (6), Fe2(CO)8 (7), and Fe(CO)3 (8), or solely complex 7 in which the ligand is bound in a eta2, mu-eta2, eta2, or eta4 fashion.All three complexes have been fully characterized by X-ray crystallography.Crystal data for complex 6: C21H1 4FeO5, monoclinic, space group P21/n, a = 6.326(2) Angstroem, b = 14.567(2) Angstroem, c = 20.504(2) Angstroem, beta = 96.91(2) deg, U = 1875(4) Angstroem3, Dc = 1.42 g cm-3, Z = 4.For complex 7: C25H14Fe2O9, space group P1, a = 9.677(5) Angstroem, b = 10.635(5) Angstroem, c = 13.471(6) Angstroem, alpha = 104.24(3) deg, beta = 105.46(4) deg, gamma = 104.75(4) deg, U = 1216.7(8) Angstroem 3, Dc = 1.56 g cm-3, Z = 2.For complex 8: C20H14FeO4, orthorhombic, space group Pbca, a = 13.397(2) Angstroem , b = 10.041(3) Angstroem, c = 26.579(2) Angstroem, U = 3575.1(8) Angstroem3, Dc = 1.39 g cm-3, Z = 8.Upon reaction with MeLi under an atmosphere of CO, all of the three complexes each gave a mixture of the expected eta4-ketene complex Fe(CO)4(eta4-PhCH = CH(C=C=O)CH = CHPh) (9) as the result of a deoxygenation-carbonylation reaction, and the new mu-alkylidene complex Fe2(CO)6(mu-eta3, eta3-C(CH=CHPh)2) (10) as the result of a deoxygenation reaction of the starting complex followed by the trapping of the intermediate alkylidene complex by Fe(CO)3.Complex 10, C23H14Fe2O6, has been fully characterized by X-ray crystallography and shown to be orthorhombic, space group Pbcn, a = 17.155(4) Angstroem, b = 7.842(2) Angstroem, c = 15.857(2) Angstroem, U = 2133.2(5) Angstroem3, Dc = 1.55 g cm-3, Z = 4.Keywords: Iron; Ketene; Alkylidene complexes; Dibenzylideneacetone
