INTRODUCTION

Tetrafluorobenzyl bromide (TFBB), by virtue of presence of 5 fluorine atoms, is a strong electrophile and hence readily combines with nucleophiles. This property results in its extensive usage in derivatization gas chromatography.  Commercially, PFBB is applied to make the corresponding alcohol and chloride.

Manufacture
The product is manufactured by allylic bromination of pentafluorotoluene.
