Used in a recently reported Al-catalyzed oxidation based on Oppenauer chemistry providing excellent yields of aldehydes and ketones. As a (1:1) complex with binol catalyzes the dynamic kinetic resolution of secondary alcohols with Novozym 435.
Trimethylaluminum solution can be used as a reagent in the synthesis of:
  • Polyhydroxylated cyclohexanes by stereoselective rearrangement of unsaturated glycosides.
  • Partially hydrolyzed trimethylaluminum (PHT) catalyst for the polymerization of olefins.
  • Methyl benzene by methylation of anisole derivatives using nickel-1,3-dicyclohexylimidazol-2-ylidene catalyst system.
