Hetero-Diels–Alder reaction of N-sulfinyl per- (or poly)fluoroaniline and N-sulfinylfluoroalkanesulfonyl amine with 1,3-dienes affords the corresponding cycloadduct 3,6-dihydro-1,2-thiazine-1-oxide which is readily converted to N-per- (or poly)fluorophenyl pyrrole and N-fluoroalkanesulfonyl pyrrole under mild reaction conditions in good yields.

The title compounds were obtained in high yield by the hydrolysis of perfluoroalkanesulfonylaminoalkylphosphites, which were prepared from the addition of dimethylphosphite to N-perfluoroalkanesulfonylimines. The molecular structure of R(F)SO(2)NH(4-CH3C6H5)CHP(O)(OMe)(2) is presented.

The reactions of N-sulfinylfluoroalkanesulfonyl amines, RfSO2NSO (1), with malonate or dialkyl phosphite gave 1:1 adducts RfSO2NHS (O) Nu [Nu = CH(COOEt)2, P(O)(OMe)2], and with alcohols or phenols formed RfSO2NH2 and the sulfites O=S(OR)2 by double addition [R=CH3, CMe3, H(CF2)2CH2, C6H5, C6F5]. Trans-sulfinylation occurred during the reaction of 1 with anilines (C6H5NH2, 4-FC6H4NH2 and C6F5NH2).
