Procedimiento

14.4 g of 2-ethyl hexanoic acid (0.1 mole), 100 cm3 of methanol, 11.4 g of trifluoroacetic acid (0.1 mole) and 8.0 g of sodium hydroxide (0.2 mole) are successively fed into a 500 cm3 glass reaction vessel provided with a magnetic stirring rod and a reflux device. The mixture is heated to reflux and 35.1 g (0.125 mole) of nickel sulfate heptahydrate is added. The mixture is heated again at reflux. Methanol is evaporated by means of a rotative evaporator and the residue is taken up in toluene. After filtration of the insoluble inorganic salts, toluene is distilled off and nickel 2-ethyl hexanoate trifluoroacetate is obtained. Its analysis corresponds to the formula C10H15O4F3Ni and it has the same characteristic bands as the product of example 1.
