A clean base-free α-hydroxylation of β-keto esters and amides has been developed, in which air was used as the oxygen source and SmI3 and I2 were applied as the catalysts, affording the corresponding α-hydroxylated 1,3-dicarbonyl products in good to excellent yields undermildconditions. Mechanism discussion shows that both oxygen atoms of dioxygen are utilized and incorporated into the product through
