Abdel-Bary, Hamed M. published the artcileReactions with coumarin: synthesis and reactions of coumarinsulfonamides, COA of Formula: C9H5ClO4S, the publication is Mansoura Science Bulletin, A: Chemistry (1997), 24(1), 161-170, database is CAplus.
Coumarin-6-sulfonyl chloride was amidated with different secondary amines to give coumarin-6-sulfonamides. The latter with hydrazine under controlled conditions effected ring-opening of the lactone ring to afford the corresponding o-hydroxycinnamoyl hydrazides. Hydrazones were obtained by condensation of the latter with aldehydes. Some reactions of the hydrazones or hydrazides were examined
