Abstract

Novel fluorinated carboxylic acid derivatives of the general formula: ##STR1## wherein R.sup.1 and R.sup.2 are independently selected from substituted or unsubstituted monovalent hydrocarbon groups, Rf is a divalent perfluoroalkyl or perfluoropolyether group, X is a hydrogen atom or triorganosilyl group, and a is equal to 2 or 3 are useful curing catalysts for RTV organopolysiloxane compositions. These fluorinated carboxylic acid derivatives are prepared by effecting hydrosilylation between alkenyl-containing fluorinated carboxylic acid derivatives and hydrosilanes in the presence of catalysts.
