Valenzisomerisierungen von C9H10-Kohlenwasserstoffen

Abstract: Kaliumcarbonat-Lasung und schiittelt anschlieDend mit Benzol aus, so erhllt man nach Abtrennen der organischen Phase, Trocknen und Eindampfen im Vakuum eine farblose, kristalline Verbindung vom Fp = 38-40 "C, der nach Elementaranalyse und spektralen Daten die Struktur des N-Ylids ( 3 ) .Trimethylammoniumbis(diathy1phosphono)methylid. zu-

“…Caled for C10HUNO: C, 74.51; H, 6.88; N, 8.69. Found: C, 74.53; H, 6.85; N, 8.69. Cyclopropanation of Benzobarrelene (11). A solution of benzobarrelene (11, 3.47 g, 22.5 mmol)25 in 50 ml of anhydrous ether containing 7.0 ml (70 mmol) of diethylzinc was stirred mechanically under a dry nitrogen atmosphere at room temperature while 6.20 g (25.0 mmol) of diiodomethane in 10 ml of dry benzene was introduced dropwise.…”

“…Benzohomobarrelenes 2 and 3. Reaction of benzobarrelene (11) with the Simmons-Smith reagent19'20 gave a four-component mixture consisting of pairs of mono and bis adducts (Scheme III). Increased reliability and some-Scheme III what improved yields resulted from the use of diethylzinc21 and this method was therefore preferred.…”
