FORMATION OF SUBSTITUTED BENZOCYCLOBUTENES THROUGH FLASH VACUUM PYROLYSIS
Schiess, Peter,Rutschmann, Suzanne,Toan, Van Vien
, p. 3669 - 3672 (1982)
Benzocyclobutenes carrying a substituent in the four membered ring are obtained in high yield from 2-methyl benzaldehydes through a reaction sequence involving a pyrolitic 1,4-elimination of HCl in the crucial step.
