Application of 5455-94-7, 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, 5455-94-7, 2,2,5,5-Tetramethyldihydrofuran-3(2H)-one, introducing its new discovery.
THE EFFECTS OF SUBSTITUENS AND SOLVENT POLARITY ON PHOTOCHEMICAL <1.3> SIGMATROPIC SHIFTS. EXPERIMENTAL EVIDENCE IN FAVOUR OF THE OCCURRENCE OF SUDDEN POLARIZATION IN ACYCLIC ALKENES
Furher experimental evidence regarding the occurence of sudden polarization in acyclic alkenes is presented.It is shown that the yield of formation of the product derived from an intramolecular photochemical <1,3>-OH shift in the 1 is dependent only on the polarity of the solvent employed.This result could be well explained in terms of a stabilization of the zwitterionic intermediate formed upon irradiation of 1 by reorientation polarization of the dipole solvent molecules.Besides this, it was found that replacement of the alkyl group at the terminal carbon atom of the C3-C9 exocyclic double bond in 1 by a phenyl substituent led to the occurence of a photochemical <1.3>-H shift.This directive effect of the substituents at the exocyclic double bond could be well explained on the basis of the sudden polarization model.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 5455-94-7. In my other articles, you can also check out more blogs about 5455-94-7
