The invention relates to a method for preparing carbene by means of deprotonation of a precursor salt using a strong base. A purpose of the invention is to enhance the synthesis of carbenes, i.e. to simplify same, to make said synthesis more economical and to obtain a liquid or solid, stable and pure form consitituting a catalytic system that is easy to store and use and that has a higher efficiency, higher yield and higher selectivity than carbene catalysts of the prior art. In order to do so, the method comprises deprotonation in a solvent including an alcohol. The invention also relates to an alcohol-containing solution and carbene, and to a solid that can be obtained from the solution, e.g. by means of sublimation. |
