摘要：
Under a catalytic amount of PTSA in aqueous or alcoholic media, activated unsymmetrical arylalkynes 1 undergo regioselective water or alcohol addition to afford successfully carbonyl compounds 2 in good to excellent yields. This new environmentally metal-free procedure, which afforded only Markovnikov adducts, is characterized by the mildness of acidic conditions and the excellent regio- and chemoselectivity.
