A PROCESS FOR THE PREPARATION OF CYCLOBUTENE-SUBSTITUTED AROMATIC HYDRO-CARBONS.

摘要

The invention is a process for the preparation of an aromatic hydrocarbon with a cyclobutene ring fused to the aromatic hydrocarbon which comprises, dissolving an ortho alkyl halomethyl aromatic hydrocarbon in an inert solvent and pyrolyzing the solution of ortho alkyl halomethyl aromatic hydrocarbon in the inert solvent under conditions such that the ortho alkyl and halomethyl substituents form a cyclobutene ring thereby forming an aromatic hydrocarbon having a fused cyclobutene ring.
