Abstract
Abstract Thioacetalization using 2??(1, 3??dithian??2??ylidene) malonic acid 1 as a nonthiolic, odorless 1, 3??propanedithiol equivalent promoted by p??dodecylbenzenesulfonic acid in water has been achieved. A range of selected carbonyl compounds 2 was converted into the corresponding dithioacetals 3 in high yields. Moreover, the thioacetalization showed high chemoselectivity between aldehydes and ketones.
