Electrolysis of carboxylic acid salts m solution causes decaboxyladve coupling similar to Kolbe reaction. Thus, eleclrolysis of 3,3,3-trifluoro-2-trifluoromethyl-propanoic acid in die presence of some of its potassium salt gives the corresponding fluoroalkane in a satisfactory yield [7d] (equation 67). 

Propanoic acid can be used to prepare the salt potassium propanoate, GHjCH COOK. Explain why potassium propanoate solution has a pH greater than 7. In your answer, you should mention the two equilibria Involved. 

Any soluble salt of propanoic acid and a strong base would be suitable. Acceptable answers include sodium propanoate or potassium propanoate. 

Kolbe noted also the formation of traces of methyl acetate and butyl valerate from electrolysis of acetate and valerate respectively. Careful analysis of reaction products by Petersen (1900) identified compounds which are today formulated as being derived from carbocations formed by loss of one electron from the alkyl radical [50]. Propanoic acid gives mostly ethene while butanoic acid and 2-methyl-propanoic acid give mostly propene. Acetate and long chain alkylcarboxylates give mostly the Kolbe type dimer hydrocarbon on electrolysis of their potassium salts in concentrated solution at a platinum electrode, using high current density and low temperatures [51].

Treatment of 3-(l-benzyloxymethylcyclopropyl)propanoic acid with various mercury(II) salts such as nitrate, trifluoroacetate and perchlorate gave the lactones 25A and 25B in 35-86% yield after aqueous potassium bromide workup. A number of related cyclopropanecarboxylic esters were reacted in the same fashion to give bromomercurio-substituted lactones 26 and 27/28 from which the mercury was removed by reduction with sodium borohydride. ...

The Perkin condensation is an aldol-type condensation in which an aromatic aldehyde (ArCHO) reacts with a carboxyUc acid anhydride, (RCH2C0)20, to give an a,j8-unsaturated acid (ArCH = CRCO2H). The catalyst that is usually employed is the potassium salt of the carboxylic acid (RCH2CO2K).
