    Description / Table of Contents: Rearrangement Products from the Reaction of 1,7-Dimethoxy-1,1,7,7-tetraphenyl-2,5-heptadiyne-4-one with Halogen Hydracids1,7-Dimethoxy-1,1,7,7-tetraphenyl-2,5-heptadiyne-4-one (4) was synthesized and the reaction with halogen hydracids studied. 4 reacts with aqueous hydrochloric acid to give the diallene ketone 1 and the cyclohexadienone 2. The reaction with hydrobromic acid and hydroiodic acid also affords cyclohexadienone derivatives.
    Notes: 1,7-Dimethoxy-1,1,7,7-tetraphenyl-2,5-heptadiin-4-on (4) wurde dargestellt; seine Reaktionen mit Halogenwasserstoffsäuren wurden untersucht. Es reagiert mit wäßriger Salzsäure zu einem Diallenketon 1 und einem Cyclohexadienon 2. Die Reaktionen mit Brom- und Jod-wasserstoffsäure liefern ebenfalls Cyclohexadienonderivate.

    Description / Table of Contents: Note on Reactions of 4-Methoxy-1-(1-naphthyl)-4,4-diphenyl-2-butyn-1-one with Hydrochloric AcidAt elevated temperature, reaction of the ethynyl ketone 1 with hydrochloric acid in tetrahydrofuran or benzene preferentially yields the phenalenone 2, while the butenone 3 is formed at room temperature in benzene or acetic acid.
    Notes: Die Reaktion des Äthinylketons 1 mit HCl liefert bei erhöhter Temperatur in wäßrigem Tetrahydrofuran und in Benzol bevorzugt das Phenalenon 2, bei Raumtemperatur in Benzol oder Eisessig das Butenon 3.
