Abstract
A process for synthesizing an organic transition metal complex compound with an atom group having an electron-donor ability, in an industrially and economically advantageous manner, without a compound having a proton-donor ability being a metal salt, and a metathesis catalyst produced with the use of the above process, are provided. A process for producing an organic transition metal complex compound in which an atom group having an electron-withdrawing ability can be converted into an atom group having a stronger electron-donor ability, by contacting an compound having a proton-donor ability with the organic transition metal complex compound with an atom group having an electron-withdrawing ability, in the presence of an basic compound, and a metathesis catalyst of which the content of an alkali metal is reduced, and which is obtainable with the use of the above process, are provided.
