sulfinamides (7) with di-t-butyl diperoxyoxalate (DBPO) in benzene at 21 or 40°C, give hyperfinesplitting (hfs) constants which indicate that the unpaired electron is slightly delocalized onto the sulfinyl group. A comparison of the hfs constants for 2 with those for structurally related sulfenamidyl and sulfonamidyl radicals indicates that the abilities of –SR, –S(O)R, and –S(O2)R to delocalize the unpaired
