[0149] (1) Preparation of modified particles
[0150] A 50 ml four-necked flask equipped with a stirrer, dropping funnel and thermometer was dried under reduced pressure, and then the air in the flask was replaced with nitrogen. The flask is equipped with 1.02 g of silicon dioxide (manufactured by Davison Co., Ltd., Sylopol 948, average particle diameter=55 μ m, pore volume=1.66 ml / g, specific surface area=309 m2) through 300 ℃ of nitrogen flow heat treatment. 2 / g). 13 ml of toluene was added to obtain a slurry, and a solution of 0.668 g (2.04 mmol) of samarium(III) isopropoxide in 17 ml of toluene was slowly added dropwise. The mixture was stirred at room temperature for 2 hours, the supernatant was removed by filtration, and the remaining solid compound was washed four times with 20 ml of toluene. Then, 30 ml of toluene was added to obtain a slurry, and 2.0 ml (4.0 mmol) of pentafluorophenol (2 mol / L, toluene solution) was slowly added. The mixture was stirred at 80°C fo...

[0159] (1) Preparation of modified particles
[0160] A 50 ml four-necked flask equipped with a stirrer, dropping funnel and thermometer was dried under reduced pressure, and then the air in the flask was replaced with nitrogen. 0.39 g (2.1 mmol) of bis(cyclopentadienyl) manganese and 30 ml of toluene were added to the flask, and the mixture was stirred. Add 0.77 g of silica (manufactured by Davison Co., Ltd., Sylopol 948; average particle diameter = 55 μm; pore volume = 1.66 ml / g; specific surface area = 309 m) through 300 ° C nitrogen flow heat treatment. 2 / g). The mixture was stirred at room temperature for 2 hours, the supernatant was removed by filtration, and the remaining solid compound was washed four times with 20 ml of toluene. Then, 30 ml of toluene was added to obtain a slurry, and 1.1 ml (2.2 mmol) of pentafluorophenol (2 mol / L, toluene solution) was slowly added. The mixture was stirred at 80°C for 2 hours, and the supernatant was removed by filtration. The ...
