Unusual Kinetic Stability of Enols to Ketonization: 1,2-Dimesityl-3-methylbut-1-en-1-ol and Related β-Alkyl-α,β-dimesitylethenols

Nadler, Ella B.,Rappoport, Zvi

, p. 2673 - 2682 (2007/10/02)

The β-alkyl-α,β-dimesitylethenols 3 and the isomeric β-alkyl-α,β-dimesitylethanones 4 (β-alkyl = Me, Et, i-Pr) were prepared and their spectral properties are reported.X-ray diffraction of the β-isopropyl enol 3d showed that the two mesityl rings are near
