Definitions
- the present invention relates to a method for synthesizing a meta-acene compound which can be used for hydrogenation of an organic synthesis catalyst, a polymerization catalyst, a low molecular weight compound or a high molecular weight compound, and the like.
- the meta-opensene compound is useful as a catalyst, and various meta-opensene compounds are known.
- a method for synthesizing an aryl metallocene compound a method known in the art is known in which a meta-mouth Sendai halide and an aryl metal compound are reacted at room temperature for a certain amount of reflux S to be used.
- a side reaction such as reduction of the meta-mouth atom occurs, and the desired product cannot be obtained in high yield, and a high arylmetallocene conjugate is obtained.
- a purification process such as recrystallization is required, which is not economical, whereas, in an aqueous medium, a meta-mouth Sendai halide (eg, a metallocene dichloride) and an aryl metal (eg, Aryl metal) and the metallocene Methods of synthesizing compounds are known (flat 2-34360, Japanese Patent Publication 63-60027,
- the arylmetacene compound, which is the objective compound, is an industrially useful catalyst for the production of a high molecular compound having high steric fiber IJ properties and a hydrogenation catalyst. There is a strong need for a product that can be easily worked up and obtained in high yield.

- the added general G (G) when the added general G (G) is 0.9 mol, the presence of an unstable reaction intermediate tends to cause a side reaction, which results in a decrease in quality and yield.
- the Grignard reagent of general formula 0) to be added exceeds 1.5 mol times of the Grignard reagent ifi, a separate step is required to connect Grignano, which complicates the production, and further increases the crystal quality.
