โœฆ Synopsis


Eingegangen am 26. Januar 1970 Die bekannte Anlagerung von Tritylnatrium und Triphenylboran an Butadien fiihrt zum Natrium-triphenyl-[trun.~-5.5.5-triphenyl-penteii-(2)-yl-(l)]-borat (lc), dessen Struktur jetzt 1H-NMR-spektroskopisch gesichert wird. 1 c liefert mit 1 n HCl unter Allyl-Umlagerung ( I .3-SE-Reaktion) 5.5.5-Triphenyl-penten-( 1) (2). Organic at-Complexes, 111 ). Structure trnd Hydrolysis o f the lit-Complex from Tritylsodiniii-Triphenylborune and Bufudiene 2 ) The known addition of tritylsodium and triphenylborane to butadieiie gives sodium-triphenyl-[trans-5.5.5-triphenyl-penten-(2)-yl-(l)]-borate (lc), the structure of which is now established by 1H-NMR-spectroscopy. An allylic rearrangement takes place in the reaction of I c with 1 n HCI (1.3-SE-reaction) to give 5.5.5-triphenyl-l -pentene (2).
