Hydride migratory aptitude

Soveral 1,1-diarylethylcne oxides have been subjected to Ihr action of magnesium bromide or boron trifluoride (Eq. 453). Again, migratory aptitude in the epoxide-isomerization process appears to l -a function of the overall substitution pattern. Thus, 1,1-diphenyi ethylene oxide and 2-methyl-1,1 -diphenylethylene oxide -J suffer hydride shifts exclusively. On the other hand, 2-ethyl-i.i-diphenylethylene oxide reportedly undergoes hydride shift and cthvl migration... [Pg.131]
