Synthetic Route of 76089-77-5, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 76089-77-5, Name is Cerium(III) trifluoromethanesulfonate, molecular formula is C3CeF9O9S3. In a Article，once mentioned of 76089-77-5
X-Ray structural analyses of the rare earth(III) trifluoromethanesulfonates (triflates) with urea derivatives are described. The reactions of anhydrous rare earth triflates with 8 equiv of tetrahydro-2- pyrimidinone (trimethyleneurea (PU)) in methanol give [M(pu)8](OTf)3 (OTf = triflate) (M = Sm: 1a; M = Y: 1b; M = Nd: 1c; M = Eu: 1d; M = Gd: 1e; M = Tb: 1f; M = Dy: 1g; M = Ho: 1h; M = Yb: 1i), and [Sc(pu)6](OTf)3 (2). X-Ray crystallographic analyses of these complexes indicate that a pair of PU ligands are interacting with each other through the hydrogen bonds. The reaction of anhydrous samarium(III) triflate with 6 equiv of 1,3-dimethyl- 3,4,5,6-tetrahydro-2(1H)-pyrimidinone (1,3-dimethyltrimethyleneurea (DMPU)) in tetrahydrofuran (THF) affords [Sm(dmpu)6](OTf)3 (3) which has a hexa- coordinated octahedral structure. Anhydrous samarium(III) triflate reacts with 5 equiv of 1,3-dimethyl-2-imidazolidinone (DMI) to give [Sm(Otf)2(dmi)5]OTf (4) which has a hepta-coordinated pentagonal bipyramidal structure. Five DMI ligands in 4 coordinate to the samarium atom in a propeller-like fashion.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Synthetic Route of 76089-77-5, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 76089-77-5, in my other articles.
