설명

일반 설명

Trimethylaluminum is a Lewis acid having wide applications in organic synthesis. It is employed in organic reactions like cross-coupling reaction, methylenation, carboalumination, cyclopropanation, and rearrangement reactions. Tebbe Reagent (methylenation agent) can be prepared in situ by reacting trimethylaluminum with dichlorobis(cyclopentadienyl)titanium.[1]

애플리케이션

Used with 4-bromo-2,6-di-tert-butylphenol (cat. no. 394378) to prepare a wide range of carbonyl compounds via the selective rearrangement of epoxides.[2][3]
