OxygenNo subtypeDioxygen
While 1·BPh4 does not react with oxygen , other complexes undergo oxidative transformation in the presence of dioxygen .
Labeling experiments with ( 18)O2 show the incorporation of one oxygen atom from dioxygen into the cleavage products .
The reaction of 2·ClO4 with dioxygen affords 2-amino-3H - phenoxazin-3-one , an auto - oxidation product of 2-aminophenol , whereas complexes 3·BPh4 , 4·BPh4 , 5·ClO4 and 6·ClO4 react with O2 to exhibit C - C bond cleavage of the bound aminophenolates .
