SF5-Substituted KetenesKetenes F5S - CR = C = O [R = H, CH3, C1. Br (2a - d )] are pre-pared by dehydration from the acids F5S - CHR -CO2H (1a-d), or in the case of R = CH3 (b) also by halogen elimi- nation with mercury. These ketenes exhibit remarkable sta-bility, increasing in the sequence R = H, CH3, C1, Br. They undergo addition reactions across the C = C double bond in known fashion. The isomerization reaction of F5S—CH = C = O (2a) to F,S=CH—COF is not shown by any of the other ke-tenes.
