Palladium-catalyzed β-acyloxylation of simple amide via sp3 C-H activation

β-Acyloxy amides are prepared in moderate to high yields by palladium-catalyzed acyloxylation of primary sp3 C-H bonds from simple amides without any special directing group. A catalytic system of Pd(OAc)2/CF3CO2H/ K2S2O8 is available to various amides with N-substituted by linear alkanes, cyclic alkanes, and electron-deficient benzyl compounds in this reaction. Acyloxylated products could be transformed easily to the corresponding β-hydroxy amides.

Oxidative esterification of homologous 1,3-propanediols

The oxidative esterification of a homologous series of diols (1,3-propanediol,2-methyl-propanediol and 2,2-dimethyl-1,3-propanediol) with methanol has been investigated using titania-supported gold, palladium and gold-palladium catalysts using molecular oxygen. The gold-palladium catalysts showed the highest activity and 1,3-propanediol was the most reactive while the additional methyl groups decreased the reactivity. However, it is possible to achieve high selectivity to methyl 3-hydroxypropionate and 2-methyl-3- hydroxyisobutyrate by mono-oxidations. Graphical Abstract: [Figure not available: see fulltext.]
