Direct-type hydroxymethylation of 1,3-dicarbonylcompounds with aqueous formaldehyde proceeded smoothly in water in the presence of Fe(NO 3 ) 3 ·9H 2 O and sodium dodecylbenzenesulfate (SDBS), to afford the corresponding products in good to high yields.

Abstract We herein report the oxidative α-azidation of carbonyl compounds by using NaN3 in the presence of dibenzoyl peroxide catalyzed by tetrabutylammoniumiodide (TBAI). By utilizing these readily available bulk chemicals a variety of cyclic β-ketocarbonyl derivatives can be efficiently α-azidated under operationally simple conditions. Control experiments support a mechanistic scenario involving
