[Bmim][Br3] is an oxidising reagent which converts alcohols into aldehydes and ketones in mild conditions and good yields; the use of the ionic liquid (IL) as both an oxidising and a brominating reagent in the one-pot synthesis of β-bromoethyl esters from benzyl alcohols and diols has also been studied.
One-pot synthesis of ω-bromoesters from aromatic aldehydes and diols using pyridinium hydrobromide perbromide

A simple and efficient one-pot procedure has been developed for the synthesis of ω-bromoesters from aromatic aldehydes and diols in the presence of pyridinium hydrobromide perbromide (PHPB) and triethoxymethane in which aldehyde reacts first with diol and the product, cyclic acetal, reacts with PHPB to give the final product, ω-bromoesters.
A new synthetic method for haloalkyl carboxylic esters from the radical ring cleavage of cyclic acetals with haloform
Hai-Xia, Lin,Liang-Heng, Xu,Nai-Ju, Huang
, p. 303 - 306 (2007/10/03)
A one-pot reaction of cyclic acetals with haloform catalyzed by AIBN(2,2'-azobisisobutyronitrile) provides a novel convenient way to prepare directly haloalkyl carboxylic esters in good yields.
How does an alkoxy group at the benzylic carbon affect the transition state of the hydrogen-atom abstraction reaction? Correlation analysis of relative rates for 14 p-Y-substituted α,α-ethylenedioxytoluenes

Correlation analysis of the relative rates for the H-atom abstraction reaction of 14 2-(4-Y-phenyl)dioxolanes (p-Y-substituted α,α-ethylenedioxytoluenes, 1-Y) by N-bromosuccinimide (NBS) shows that the spin-delocalization effect is also operating at the transition state of the H-atom abstraction reaction and that the ethylenedioxy group at the benzylic carbon makes the spin-delocalization more observable than do two methyl groups.
