Procedure

In Example 3, hydrogenation reaction was conducted under the same condition as Example 1 for THF diluted solution concentration of the substance to be reduced, its flow rate, and hydrogen 9 flow rate, using 2,4-diphenyl-4-methyl-1-pentene as the substance to be reduced. The reaction time was within five minutes. The analytical result of the reaction product by 1H-NMR showed almost complete hydrogenation of 2,4-diphenyl-4-methyl-1-pentene, and 2,4-diphenyl-2-methylpentane was obtained at about 100% yield (See FIG. 6.).
