α-Halogenation of carbonyl compounds: Halotrimethylsilane-nitrate salt couple as an efficient halogenating reagent system

A mixture of chloro/bromotrimethylsilane and nitrate salt is found to be an effective reagent system for the α-chlorination/bromination of carbonyl compounds. The reaction occurs under mild conditions yielding the products in moderate to good yields.

A convenient synthesis of 2,2-dibromo-1-arylethanones by bromination of 1-arylethanones with the H2O2-HBr system

1-Arylethanones and related compounds are brominated in dioxane with the H2O2-HBraq system, resulting in the replacement of two hydrogen atoms in the methyl group with bromine. The reaction is also accompanied by bromination of the aromatic ring provided that the latter contains electron-donating substituents. The reaction proceeds rapidly (20 min) and results in complete conversion of ketones to give 2,2-dibromo-1- arylethanones in yields up to 86%. Georg Thieme Verlag Stuttgart.
