A Novel Cyclisation Reaction of Benzil
Cremlyn, Richard J.,Shode, Olufemi O.,Swinbourne, Frederic J.
, p. 2181 - 2184 (2007/10/02)
Benzil reacts with chlorosulphonic acid to give 3-chloro-2-phenylbenzofuran-6,4'-disulphonyl dichloride.The product was characterised as the corresponding bis-dimethylsulphonamide (1), and a mechanism has been proposed for the chlorosulphonation reaction.
