Synthesis of Metal Trifluoroacetates

This section will describe the range of preparative methods that have been used to obtain metal trifluoroacetates, each being illustrated by selected examples. However, no attempt will be made to give a comprehensive list of the compounds synthesized by any particular route. 

Trifluoroacetate complexes have also been obtained by the dis- 

Compound [Cr(C0)g(02CCF3)] may be prepared by oxidative substitution of Ag(02CCF3) or Hg(02CCF3)2 on [Cr2(CO)io] (218). Transition metal hydrido complexes have been obtained by oxidative addition reactions of trifluoroacetic acid which often lead to the formation of trifluoroacetato complexes. Equation (3) is an example of such a 

Trifluoroacetato complexes of transition metals have also been obtained from oxidative elimination reactions in which neutral tt-acceptor ligands have been displaced in reactions with trifluoroacetic acid. These reactions may lead to hydrido complexes [Eqs. (6) (253) and (7) (26)] or they may not [Eqs. (8) (39) and (9) (19)]. 

Reaction (9) presumably proceeds via an intermediate analogous to that produced in Eq. (4). Allyltrifluoroacetate effects oxidative displacement
