- IP value (7.75 eV)8 for C,N-diphenylnitrone implies that its HOMO lies somewhat higher than the HOMO of the corresponding C-phenyl-N-methylnitrone (IP = 8.01 eV)8; this difference might account for the observed shift in regioselectivity

- The replacement of Ph—P by Me—P substituent in the phosphine oxide results in similar reversal of the preferred regiochemistry. Cf. ref. 6.
- Due to complexity of the 1H NMR spectra caused by extensive proton-phosphorus coupling the stereochemical assignment should be regarded tentative. The observed formation of only one of the two possible 4-substituted stereoisomers in each studied case is most likely to originate from the preference for a transition state in which phosphinyl group and nitrone C-substituent are oriented away from each other to avoid unfavourable interactions
