Treatment of substituted ethylenes CH2=CH-X (X: CN, CH3CO) or ethylene
oxides YCHCH2O (Y: H, CH3, ClCH2) with sodium perfluoroalkanesulfinat
es R(f)SO(2)Na, (R(f): C4F9, ClC4F8) which were obtained from deiodosu
lfination reactions of R(f)I with Na2S2O4, gave 2-substituted ethyl pe
rfluoroalkanesulfinates in moderated yields.
