Abstract
The reaction of triethylaluminium and methyl methacrylate (MMA) was followed at room temperature in sealed NMR tubes. Hydrolysed reaction products were also analysed. Ethylation of MMA occurs only when MMA/A1 < 1.0. At higher ratios a strong, unreactive 1 1 complex prevails. Evidence presented suggests that a second 1 2 complex is responsible for the reactions at lower ratios. The normal reaction is carbonyl addition: twofold carbonyl adducts of the type: CH 2CMeCEt 2OAl, forming rapidly. Subsequent changes appear to involve only slow exchange or association of these ethylaluminium alkoxides. Reduction of the carbonyl group occurs to a minor and irreproducible extent. There is no evidence for 1 4 attack on MMA.
