Description

Application

Triethylaluminum solution can be used:

• As a reagent in Alumino-Mannich reaction, where it reacts with iminium ion substrates for which the corresponding Petasis borono-Mannich reaction is unsuccessful.
• In the synthesis of macrocyclic binuclear aluminum complexes with efficient activities toward ring-opening polymerization of ε-caprolactone.
• To promote Claisen rearrangement of allyl vinyl ether derivatives along with the transfer of ethyl group to aldehydic carbon.
• As a reagent for copper-catalyzed asymmetric conjugate addition of alkenyl- and alkylalanes to α,β-unsaturated lactams.
• As a precursor to synthesize diethylaluminium cyanide, which is used as hydrocyanating reagent.
