Selective oxidation of alkenes in water to ketones using molecular oxygen as the oxidant is mediated by rhodiumporphyrincomplexes through observed beta-hydroxy alkyl complexes.

Deuterated analogues of the free radical trap DEPMPO: synthesis and EPR studies
Three analogues of 5-diethoxyphosphoryl-5-methyl-1-pyrroline N-oxide (DEPMPO, 1) labelled with two (1-d2), five (1-d5) or seven (1-d7)
2H were synthesized and used to trap the tert-butylperoxyl radical. The EPR spectra of 1-d2-OOBut and 1-d7-OOBut spin adducts exhibited more straightforward patterns and better signal to noise ratio than those obtained with 1 or 1-d5. The use of the easily available 1-d2 as spin trap could help significantly the analysis of the EPR signals when the signal of either superoxide or alkylperoxyl spin adduct is superimposed with the signals of other spin adducts.
