Brosyl group

In organic chemistry, brosyl (or para-bromophenylsulfonyl) group is a functional group with the chemical formula BrC6H4SO2 and structure Br−C6H4−SO2−R.

This group is usually introduced using the compound brosyl chloride, BrC6H4SO2Cl, which forms sulfonyl esters and amides of p-bromophenylsulfonic acid.

The term brosylate refers to the anion of p-bromophenylsulfonic acid (BrC6H4SO−3).
