a
The values of the integrals of the underlined NMR peaks were used to determine the
amount of compounds. bIdentified from the 1H NMR pattern, i.e., septet for the CH, and doublet
for CH3. c was observed during the decomposition of TEMPO-PEstMe in C6D6 in the absence of
scavenger. d From authentic sample kindly provided by Prof. Grecci. e For reference see 9. .
