The synthesis of arylsulfonyl halides

Abstract
The synthesis of a series of arylsulfonyl chlorides by a modification of the Sandmeyer reaction as developed by Meerwein et al1 is described. This method seems applicable to the preparation of arylsulfonyl bromides, but not for arylsulfonyl fluorides. The characteristic IR vibrations of the SO2‐group are tabulated for the various arylsulfonyl halides.
