The First Synthesis of p-Cl- and p-F-Phenylverbenene

Abstract

The first synthesis of 4´-X-phenylverbenene (X = F and Cl) via reaction of myrtenal with 4� -X phenylmagne- sium bromide and Bi(NO3)3 is described. Verbenene is formed due to the electron-withdrawing effect of the 4� - electronegative group, either fluorine or a Cl-Bi complex.
