Abstract
Abstract Fluoroaliphaticsulfonyl substituted methanes have the general formula ##STR1## WHEREIN R f is a fluoroaliphatic radical R 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.
