CARBOCATIONIC CYCLIZATIONS INITIATED BY DEHALOGENATION OF UNSATURATED α-BROMOIMINE
Begue, J.P.,Bonnet-Delpon, D.,Charpentier-Morize, M.,Richard, A.
, p. 5681 - 5682 (2007/10/02)
Electrophilic dehalogenation (AlCl3-CH2Cl2) of the ω-olefinic α-bromo α'-phenyl imine 1 leads by two successive carbocationic cyclizations to the 5-9 methanobenzocyclooctene system.
