Fluoroaliphaticsulfonyl substituted methanes have the general formula ##STR1## WHEREIN R.sub.f is a fluoroaliphatic radical R.sub.3 is a radical selected from a group consisting of alkyl, perfluoroaliphatic or aryl. The fluoroaliphaticsulfonyl methanes may be condensed with aldehydes or N-formyl compounds to produce fluoroaliphaticsulfonyl substituted ethylenes which are useful as catalysts.
氟烷基磺酰取代
甲烷的通式为##STR1## 其中R.sub.f为氟烷基基团,R.sub.3为从烷基,
全氟烷基或芳基中选择的基团。这些氟烷基磺酰
甲烷可以与醛或N-甲酰化合物缩合,产生有用的作为催化剂的氟烷基磺酰取代
