Synthesis of a base-stabilized alumoxane: preferential hydrolysis of an aluminium–amido over an aluminium–alkyl
Abstract
The preferential hydrolytic cleavage of an A1-N versus an A1-C bond allows for isolation of the base stabilized alkylalumoxane,[(tBu)2A1{NH(Me)CH2CH2NMe2}]2(µ-O), from the hydrolysisof the intra-molecularly stabilized amino-amide compound, (tBu)2A1[N(Me)CH2CH2NMe2], providing a possible general route to alkylalumoxanes.
