Abstract
The present invention relates to a method for preparing a cocatalyst compound using an anhydrous hydrocarbon solvent, and a cocatalyst compound prepared thereby.
Claims5
A method for preparing a compound represented by [(C18H37)2N(H)Me]+[B(C6F5)4]−, the method consisting of:
- a step of reacting [K]+[B(C6F5)4]− and [(C18H37)2N(H)Me]+[Cl]− in the presence of the anhydrous hydrocarbon solvent and in absence of water under an inert atmosphere using a standard glove box and Schlenk technique at a temperature of 0 to 50° C. for 15 minutes to 5 hours to obtain a mixture, and
- a step of separating and purifying the compound represented by [(C18H37)2N(H)Me]+[B(C6F5)4]− from the mixture,
- wherein the compound represented by [(C18H37)2N(H)Me]+[B(C6F5)4]− shows at least two peaks in a range of 1.60 ppm to 2.10 ppm in a 1H NMR (500 MHz, C6D6, and standard material TMS) spectrum.
