4,4-Diphenyl-1-butene (compound 1, 0.40 mmol) and pentamethyl disiloxane (0.6 mmol) were dissolved in hexane (2.0 ml), added with poly (methylphenylsilane)-supported platinum (200 mg, 5.5 mol %) prepared in Example 10A and stirred at 20° C. for 2 hr. The filtrate was washed with hexane after separation from catalyst, concentrated, and purified by silica gel column chromatography using hexane as an eluting solvent. (4,4-Diphenylbutyl) pentamethyl disiloxane was obtained as oil without color (140 mg (98%)) and 1,1-diphenyl butane was obtained (2 mg (yield 2%)).
