Islam, A. M. published the artcileSynthesis and biological activity of coumarin sulfonamides and related compounds, Name: Coumarin-6-sulfonyl chloride, the publication is Indian Journal of Chemistry, Section B: Organic Chemistry Including Medicinal Chemistry (1982), 21B(5), 487-9, database is CAplus.

The coumarins I [R = BuNH, PhCH2NH, 2-furylmethylamino, (un)substituted anilino, (un)substituted phenoxy; R1 = R2 = H; X = O] were prepared by treating 6-coumarinylsulfonyl chloride with RH. Some I (R1 = R2 = H) were converted to I (R1 = R2 = Br, R1 = H, R2 = NO2, R = R1 = H, X = S, NOH). Some I had bactericidal activity.
