General description

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.


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.

BRCA1-associated protein 1 (BAP1) is a tumour suppressor gene frequently inactivated in mesothelioma, rarely also in association with germline mutation. BAP1 mutations have been associated with improved prognosis and distinct clinicopathological features. We sought to determine the clinicopathological significance of...
