Process for preparing organic alkali metal compound and organic transition metal compound

A process for preparing an organic alkali metal compound represented by the following formula (3), comprising adding an olefin compound represented by the following formula (2) in the reaction of an active proton-containing compound represented by the following formula (1) with an alkali metal compound in the presence of solvents;

• wherein the solvents are a mixture of a hydrocarbon and an aliphatic ether in which the mixing ratio by volume of hydrocarbons/aliphatic ethers is in the range of 95/5 to 85/15;
• RHp (1)
• wherein R is a hydrocarbon group or an amino group and may contain a halogen atom, a silicon atom, an oxygen atom or a nitrogen atom, H is an active proton, and p is the number of hydrogen atoms abstracted in the reaction with the alkali metal compound,
• wherein Ra to Rc are each an atom or a group selected from a hydrogen atom, a hydrocarbon group, a heteroatom-containing group and a silicon-containing group and may be the same as or different from each other, and the neighboring substituents may be bonded to each other to form a ring,
• RNp (3)
• wherein R is a hydrocarbon group or an amino group and may contain a halogen atom, a silicon atom, an oxygen atom or a nitrogen atom, N is an alkali metal atom, and p is the same value as in the formula (1).
