Bromomagnesium hexamethyldisilazide

Reaction with Carbonyl Compounds. Although seldom used in comparison with bromomagnesium diisopropylamide, bromomagnesium hexamethyldisilazide has the unique feature of high solubility in organic solvents. [Pg.85]

Bromomagnesium hexamethyldisilazide and bromomagnesium diisopropylamide were the most effective of several magnesium bases examined for selective formation of the more substituted silyl enol ether fromketones (eq 1). Less-hindered ketones gave mainly aldol products. ... [Pg.85]

Related thermodynamic enolization control has been observed using metallated hexamethyldisilazide to give the more substituted bromomagnesium ketone enolates. Metallation reactions of HMDS to yield Li, K, and Na derivatives are well known and the resulting nonnucleophilic bases have found extensive applications in organic synthesis. ... [Pg.319]
