Abd El-Bary, H. published the artcileReactions with coumarin. II, COA of Formula: C9H5ClO4S, the publication is Modelling, Measurement & Control, C: Energetics, Chemistry, Earth, Environmental & Biomedical Problems (1995), 47(1), 43-8, database is CAplus.

Coumarin-6-sulfonyl chloride reacted with o-, m-, p-phenylenediamine to give the sulfonamides I (R = 2-, 3-, 4-H2NC6H4). Phenylisocyanate or phenylisothiocyanate reacted with I yielding the urea derivatives Condensation of I with acetaldehyde or acetophenone gave the imines. The sulfonic acid esters were formed through condensation of coumarin-6-sulfonyl chloride with phenolic derivatives
