Uses

3,5-Dichloro-2-hydroxybenzenesulfonyl chloride is used in the synthesis of (1R,2R)-(+)-1,2-(3,3?,5,5?-tetrachloro-2,2?-dihydroxydibenzenesulfonamido)-1,2-diphenylethane1 and (1R,2R)-(+)- 1,2-(3,3?,5,5?-tetrachloro-2,2?-dihydroxydibenzenesulfonamido)cyclohexane. It was used as chromogenic system in one-step kinetic method for the determination of 5?-nucleotidase.

Enantioselective addition of diethylzinc to benzaldehyde catalyzed by chiral titanate complexes with helical ligands

Enantioselective alkylation of benzaldehyde with Et2Zn has been studied. This reaction is catalyzed by helical titanium complexes of tetradentate ligands and has been found to give good to excellent enantioselectivities.
