Kurzzeitpyrolyse, VI Ringverengungen durch CO-Eliminierung aus cyclischen Carbonylverbindungen / Short Time Pyrolysis, VI Ring Contractions by CO-Elimination from Cyclic Carbonyl Compounds
An one-step synthesis of benzocyclobutene (2) by gas-phase pyrolysis of indane-2-one (1) has been found. By the same method indane-1-one (3) and naphthoquinone(1,4) (5) gave indene-1 -one (4) and fluorene-9-one (7) formed biphenylene (8).
