ISOTOPIC EXCHANGE OF HYDROGEN IN THE TRIFLUOROACETIC ACID ESTERS. 1. THE HYDROGEN EXCHANGE OF ALKYL TRIFLUOROACETATES WITH TRIFLUOROACETIC ACID (in Russian)
The kinetics of the reaction, recently uncovered (Izvest. Akad. Nauk, Otdel. Khim. Nauk, 378(1961)), on the isotopic exchange of the H of trifluoro acetates with deuteriumenriched water-free trifluoroacetic acid, was further examined, studying the corresponding reaction of alkyl trifluoro acetates. It was found that in ternary compounds the H--D exchange takes place with a relatively high rate but it is inhibited in the secondary and primary esters. The exchange reaction of the ternary esters is further enhanced by increasing the acidity of the system by the addition of trifluoro acetic acid dissolved in sulfuric acid; even this addition was not able to cause a noticeable reaction in the primary esters. It is assumed that the exchange reaction is due to the ionization of the esters and the formation of carbonium ions which are capable to participate in the exchange. (TTT)
