Bulk gold powder (～50 μm) catalyzes the oxidative dehydrogenation of amines to give imines using amine N-oxides (R3N-O) as the oxidant. The reaction of dibenzylamine (PhCH2-NH-CH2Ph) with N-methylmorpholine N-oxide (NMMO) in the presence of gold powder at 60 °C produced N-benzylidenebenzylamine (PhCH=N-CH2Ph) in 96% yield within 24 h. Benzyl alcohol was oxidized by NMMO to benzaldehyde in >60% yield in the presence of gold powder. Although O2 was previously shown to oxidize amines in the presence of bulk gold, it is surprising that gold is also capable of catalyzing the oxidation of amines using amine oxides, which are chemically so different from O2.

Oxazolidinones are prepared from the palladium-catalyzed carbonylation of β-aminoethanols under mild conditions.With N-alkyl-substituted substrates, conditions for double carbon monoxide incorporation to give morpholinediones have been discovered.Cyclic carbonates can be prepared from the carbonylation of diols.The carbonylation of N-phenyl-1-aminopropane-2,3-diol can give either the carbonate or oxazolidinone as the major product depending on the reaction conditions.
