Csq. Lew et al., DIAZO-COUPLING REACTIONS OF CYCLOHEPTATRIENOLS - A COMBINED EXPERIMENTAL AND THEORETICAL-STUDY, Journal of the Chemical Society, Chemical Communications, (2), 1995, pp. 175-176
Isomeric cycloheptatrienols 1, 2 and 3 are found to undergo ketonizati
ons as well as diazo-coupling reactions via three different pathways;
experiments and ah initio calculations suggest that the 2-hydroxy grou
p provides a small but effective stabilization effect on norcaradiene
