Synthetic Route of 33100-27-5, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane, molecular formula is C10H20O5. In a Article,once mentioned of 33100-27-5
Addition of CpM (Cp = C5H5; M = Li, Na, K, Cs) to Cp2E (Cp = C5H5; E = Sn, Pb) produces pi-anions of general formula [Cp2x+1Ex]-. Multidecker anions (with x > 1) can be prepared for Pb if crown or cryptand ligands coordinate the alkali metal cations. The syntheses and structures of the new complexes [Cp3Sn]-·[Li(12-crown-4)2]+ (2), [Cp2Pb(mu-Cp)Na·(15-crown-5)] (3), [Cp5Pb2]-[K(2,2,2-crypt)]+·THF (4), [Cp2Pb(mu-Cp)Pb(mu-Cp)Cs(18-crown-6)] (5), and [Cp5- Pb2]-[Li(12-crown-4)2]+·2THF (6) are reported. This study, together with that on [Cp9-Pb4]-[Cp5Pb2] -[{Li(12-crown-4)2 +}2] (1), which we have communicated previously, indicates that charge separation and lattice energy considerations subtly control the aggregation of the multidecker Pb(II) anions involved. These factors allow the potential control of the anion homologues formed by changing the solvation sphere of the alkali metal cations. However, as is illustrated by the structures of 1 and 6, which contain the same [Li(12-crown-4)2]+ countercation, in certain cases structural modification can be controlled by the reaction employed.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 33100-27-5 is helpful to your research., Synthetic Route of 33100-27-5
