Photochemisch induzierte 1,2-Bis(dialkylaluminierung) von Diphenylacetylen

Abstract: Die '3C-NMR-Spektren[51 (Tabelle 1) von (2) und (3) sprechen durch das Auftreten von jeweils nur sieben Signalen fur eine q4-Koordination des Tetraphenylcyclobutadiens. Auch bei Einwirkung von Kohlenmonoxid (Toluol, 1 atm) wird deutlich, daB COD in (2) fester komplexiert ist als COT in (3). So nimmt 1 mol (3) bereits bei 20 "C 4 mol CO unter Verdrangung der beiden Liganden auf, wahrend bei (2) hierzu 50 C erforderlich sind. Aus Tetraphenylcyclobutadien entsteht dabei Octaphenylcyclooctatetraen (5).(2) und (3)… Show more

“…The reactions of aluminum compounds (alkyls, hydrides, and halides) with alkynes have been explored extensively . The resulting aluminum vinyl derivatives undergo interesting thermal and photoinduced rearrangements and have proved to be valuable precursors for organic chain growing reactions and in the reaction of unstable Al(I) compounds with alkynes .…”
