- (a) one or more suitable palladium components;
- (b) one or more suitable heteropolyacid or copper components;
- (c) one or more surfactants selected from the group consisting of quaternary ammonium salts, alkali metal sulfates, alkali metal salts of alkanoic acids, alkali metal salts of alkaryl sulfonic acids, and 1-alkyl pyridinium salts;
- and
- (d) at least one fluorocarbon compound conforming to the empirical formula:
