Parham-type cyclization benzocyclobutanes

The utility of o-quinodimethanes as very reactive diene components in Diels-Alder reactions has stimulated interest in the synthesis of benzocyclobutanes, their most commonly used precursors. A full account has been given of the preparation of benzocyclobutanols (47) from o-halostyrene oxides (46), " whereas a related Parham-type cyclization can be used to convert bromoethyl-benzenes (48) into benzocyclobutanes (49). Two rather different approaches... [Pg.282]
