A new, simple, base-mediated addition reaction of 1,2-bis(phenylsulfonyl)ethane to ketones has been developed for the synthesis of 1-aryl-4-(phenylsulfonyl)butan-1-ones. This method represents the first example of preparing sulfones using 1,2-bis(phenylsulfonyl)ethane as the sulfone resource.
Key words
