Abstract
Treatment of substituted ethylenes CH2[dbnd]CH—X (X: CN, CH3CO) or ethylene oxides YCHCH2O (Y:H, CH3, CICH2) with sodium perfluoroalkanesulfinates R1 SO2Na, (R1: C4F9, CIC4F8) which were obtained from deiodosulfination reactions of Rf I with Na2S2O4, gave 2-substituted ethyl perfluoroalkanesulfinates in moderated yields.
