PROBLEM TO BE SOLVED: To obtain an organosilicone compound by hydrosilylating an arylvinyl compound to introduce a silyl group in a site-selective way onto theα-site of the arylvinyl compound. SOLUTION: This organosilicone compound of formula (I) is obtained by reaction between an organometallic compound of formula (II), a silane of formula (III) and an aryl derivative of formula (IV) (wherein, Ar is an aryl; R1, R2 and R3 are each H, a halogen atom, hydrocarbon group, alkoxy or the like; R4 is H or the like; M is a group 3 to 5 or lanthanide-series metal; L1 and L2 are each a non-localized cyclicη5-coordination-based ligand; and Z1 and Z2 are each an eliminable group). Specifically, the process is as follows: the organometallic compound of formula (II) is mixed with the silane of formula (III) followed by further mixing the aryl derivative of formula (IV); wherein, alternatively, as L1 and L2, a bulky non-localized cyclicη5-coordination-based ligand is each used; and optionally, the silyl group in the organosilicone compound of formula (I) thus obtained is oxidized into a hydroxyl group.
