Abstract
The processes of 1-ethyl-3-R-alumolane (R= n-Alk, iBu, Ph, Bn, SiMe3, p-methoxybenzyl) self-association in toluene, benzene, cyclohexane and dichloromethane were studied for the first time by multinuclear NMR spectroscopy and quantum chemical modeling. Using 1H, 13C, and 27Al NMR spectroscopy in non-polar solvents, the examined alumolanes were identified as an equilibrium mixture of isomeric dimers formed via coordination of Al-C ring bonds of the metallacycle. The structures of twenty energetically more favorable dimers were found on the basis of thermodynamic parameter calculations of self-association reactions. A multicenter character of binding in аlumolane dimers was proposed.
