Epoxidation with nitro complexes of metals

Practical effiecient catalytic epoxidations for large scale operations involve either 0 or peroxidic compounds (alkyl 

The first two reports in which oxygen transfer catalysis from nitro complexes was applied to the epoxidation of olefins were published simultaneously. 

O-tracer studies have shown that one O-atom is transferred from the 

Pd(CH CN)2Cl2 as cocatalyst [125]. The nitro group is first transferred 

The solution structure of 4 and its conversion to the norbornene oxide has been studied [127,128]. Selective epoxidation via pure 0 atom transfer occurs in aprotlc solvents in the absence of nucleophiles. The latter would cleave the Pd-C bond to afford chlorohydroxy- and chloronitronorbornanes.
