A simple and efficient bromoazidation of alkenes using PTT and TMSN 3 in ionic liquid
A simple and efficient one-pot method has been described for the bromoazidation of alkenes using phenyltrimethylammonium tribromide (PTT) and TMSN3 in ionic liquid. The bromoazides have been obtained in good to excellent yield from various alkenes such as styrenes, chalcones, and cycloalkenes at room temperature.

A simple and efficient PTT-mediated synthesis of a-azidoketones in [bmim][BF4] ionic liquid
A simple and efficient one-pot method has been described for the direct synthesis of α-azidoketones from various ketones possessing a-hydrogen by reaction with phenyltrimethylammonium tribromide (PTT) and subsequent treatment with NaN3 in ionic liquid. The procedure gives high yield and the ionic liquid can be reused.
