FORMATION OF 1-CHLOROBENZOCYCLOBUTENE, ANTHRACENE OR BENZOFURAN BY FLASH VACUUM PYROLYSIS
Hussain, Amjad,Parrick, John
, p. 609 - 612 (2007/10/02)
Pyrolysis of o-substituted benzylidene chlorides is shown to be a useful route to 1-chlorobenzocyclobutene, anthracene or benzofurans; evidence is given for a carbene intermediate in the pyrolysis of o-methoxybenzylidene chloride.
