Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To p-azidotoluene (2.2 mM) prepared as above was added N-bromosuccinimide (2.48 mM), and azo-isobutyronitrile (0.214 mM) in anhydrous benzene (5 ml). This was left to reflux for 5 hours, with the reaction being monitored by TLC. The organics were extracted into diethyl ether (3×15 ml), and water, dried over magnesium sulphate, and the excess solvent removed under vacuum. The p-azidobenzyl bromide formed was isolated using chromatographic techniques. This was left to reflux for 5 hours, with the reaction The organics were extracted into diethyl ether (3×15 ml), and water dried over magnesium sulphate the excess solvent removed under vacuum

Procedure: A mixture of p-azidotoluene (3.9 g), N-bromosuccinimide (5.5 g) and azobisisobutyronitrile (1.0 g) in carbon tetrachloride (30 ml) was heated under reflux in the dark under nitrogen for 18 h. The reaction mixture was allowed to cool to room temperature and the solvent was removed in vacuo. The residue was dissolved in ether (50 ml) and filtered. Evaporation of solvent gave an oil (6.5 g) which was chromatographed on silica gel (200 g, Merck 7734). Elution with petroleum ether (b.p.40°-60°) gave the title compound as an oil (2.37 g). I.R. (Neat) 2120 cm-1. was heated under reflux in the dark under nitrogen for 18 h the solvent was removed in vacuo The residue was dissolved in ether (50 ml) filtered Evaporation of solvent
