Abstract
The silver ion‐catalysed ring‐opening of 2‐t‐butyl‐1‐chloro‐1‐fluoro‐2‐methyl‐cyclopropane (see Scheme 2) gave the expected mixture of primary and tertiary fluoroalkenols, whereas a tricyclic analog (bornane‐spiro‐chlorofluorocyclopropane) (see Scheme 3) exclusively underwent a Wagner/Meerwein rearrangement upon ionization to lose finally a proton affording a 2‐fluoro‐1,4‐diene.
