Unambiguous Proof for Alcoxycarbonyl-group Migration in Wagner-Meerwein Rearrangements
Berner, Daniel,Dahn, Hans,Vogel, Pierre
, p. 2538 - 2553 (1980)
In HSO3F/SO2ClF the β-hydroxy esters Ph-CHOH-CMe2-COOR (1, R=Me, Et) are doubly protonated, then transformed into the fluorosulfates 7 and (partly) into the fluorides 8.At -15 deg C, both 7 and 8 undergo a rearrangement, forming derivatives of Me2C=C(Ph)C
