ESR spectra of spin-adducts of hydroxyalkyl radicals with perfluoro-4-methyl-2-pentene
摘要:
A study was carried out on the ESR spectra of the spin-adducts of hydroxyalkyl radicals with perfluoro-4-methyl-2-pentene (I) formed upon the photolysis of alcoholic solutions of this perfluoroolefin. The stable conformational positions of the substituents in the spin-adducts depend on the structure of the hydroxyalkyl radicals. The spin-adducts are annihilated as a consequence of hydrogen atom abstraction as indicated in a preparative experiment.
Radical addition of aliphatic alcohols to internal perfluorinatedolefins has been studied. The process occurs non-stereoselectively to give equimolar mixtures of diastereoisomers in all cases.
