Sodium tribromoacetate

The use of sodium tribromoacetate as the dibromocarbene precursor has been investigated and found to provide the Ciamician-Dennstedt product in higher yield than the traditional alkoxide/alcohol reaction conditions. Deprotonation of bromoform with sodium ethoxide in ethanol and reaction of the resultant carbene with 6 provides quinoline 9 in 9% yield thermolysis of sodium tribromoacetate in the presence of 6 furnishes 9 in 20% yield (Scheme 8.3.3). [Pg.351]

This organometallic reagent is prepared in 85-95% yield by the reaction of mercuric chloride and sodium tribromoacetate in the molar proportion 1 2.5-3.0 in monoglyme. The reagent is a convenient source of dibromocarbene. Thus it reacts with cyclohexene in refluxing benzene (N2) to give dibromonorcarane in 54% yield.1... [Pg.19]
