The structure of tribenzyloxyaluminium and some related alkoxides

Abstract

Infrared spectroscopic evidence for the degree of association of tribenzyloxyaluminium and related compounds is reported. Molecular weights of tribenzyloxyaluminium have been determined ebulliometrically over a range of temperatures and the findings correlated with the temperature-dependent ¹H n.m.r. spectrum. The primary equilibria between associated species in this series can be detected from their ¹H n.m.r. spectra and in some instances evidence of a secondary association is presented.
