Chemistry:Brosyl

In organic chemistry, brosyl (or para-bromophenylsulfonyl) is a functional group with the chemical formula BrC₆H₄SO₂. 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 (BrC₆H₄SO₃⁻).
