Reference of 1293-65-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1293-65-8, 1,1′-Dibromoferrocene, introducing its new discovery.
Carbosilane-supported (p-cymene) ruthenium ferrocenyl phosphines in the beta-oxopropyl ester synthesis
The synthesis and characterization of a series of carbosilane-supported ferrocenyl phosphine ruthenium complexes of type SiMe4-n(Fe(eta5-C5H4SiMe2(CH2)3)((eta5-C5H4PR2)RuCl2(eta6-p-cymene)))n (p-cymene = 1-i-Pr-4-Me-C6H4; n = 2: 10a, R = Ph; 10b, R = cC6H11; 10c, R = 2-(5-Me)C4H2O); n = 4: 11a, R = Ph; 11b, R = cC6H11; 11c, R = 2-(5-Me)C4H2O)) is described. For comparative reasons, the non-immobilized ferrocenyl phosphine ruthenium complexes [FcPR2(RuCl2(eta6-p-cymene))] (Fc = Fe(eta5-C5H4)(eta5-C5H5); 9a, R = Ph; 9b, R = cC6H11; 9c, R = 2-(5-Me)C4H2O) were prepared. The molecular structure of 9c in the solid state is reported confirming the expected tetrahedral coordination sphere about the phosphorus atom and the “piano-stool” geometry about ruthenium. The ruthenium complexes 9-11 are catalytically active in the addition of benzoic acid to propargyl alcohol to form beta-oxopropyl benzoate. The obtained activities and productivities show that a good solubility of the catalyst is necessary for a successful catalytic reaction. Furthermore, the rate of the reaction can be influenced by using less basic and electron-withdrawing phosphine ligands.
