Popis: | It has been established that 1, 2, 4, 5-tetrafluoro-3, 6-bis (vinylsulfinyl)- and 1, 2, 4, 5-tetrafluoro-3, 6bis(vinylsulfonyl)benzenes react with 2-aminoethanol by nucleophilic addition at the activated double bond with replacement of fluorine atoms on the benzene ring by the amino group of 2-aminoethanol to give 4, 9-bis(2 hydroxyethyl)-5,10-difluoro-1, 2, 3, 4, 6, 7, 8, 9-octahydrobenzo[1, 2-b; 5, 4-b]di-1, 4-thiazine 1,6-dioxide and 1, 1, 6, 6-tetraoxide respectively. |
