Hexafluoroisobutylene
Hexafluoroisobutylene is an organofluorine compound with the formula (CF3)2C=CH2. This colorless gas is structurally similar to isobutylene. It is used as a comonomer in the production of modified polyvinylidene fluoride. It is produced in a multistep process starting with the reaction of acetic anhydride with hexafluoroacetone.[1] It is oxidized by sodium hypochlorite to hexafluoroisobutylene oxide. As expected, it is a potent dienophiles.[2]
