## Abstract

Provided is an organosilane compound expressed by the following general formula (1): where: Ar represents a divalent aromatic organic group, such as a phenylene group; R1 represents a hydrogen atom or the like; R2 to R6, which may be the same or different from each other, each represent a hydrogen atom or the like; and X represents a reactive substituent, such as a halogen atom.

## Claims

### Claim 1

An organosilane compound, expressed by the following general formula (1):
wherein:
Ar represents any one divalent aromatic organic group selected from the group consisting of a phenylene group, a biphenylylene group, a naphthylene group and a pyridylene group;
R1 represents any one of a hydrogen atom and alkyl groups having 1 to 4 carbon atoms;
R2 to R6, which may be the same or different from each other, each represents any one substituent selected from the group consisting of a hydrogen atom, a methyl group, an ethyl group, a propyl group, a butyl group, an isopropyl group, a pentyl group, a hexyl group, and a cyclohexyl group; and
X represents any one reactive substituent selected from the group consisting of a halogen atom, a magnesium halide, a zinc halide, a stannyl group which may have a substituent, a boranyl group which may have a substituent, and a triflate group.

### Claim 2 (depends on 1)

The organosilane compound according to claim 1, wherein Ar in the general formula (1) is the phenylene group.

### Claim 3 (depends on 1)

The organosilane compound according to claim 1, wherein R1 in the general formula (1) is any one selected from the group consisting of a methyl group and an ethyl group.

### Claim 4 (depends on 1)

The organosilane compound according to claim 1, wherein X in the general formula (1) is any one selected from the group consisting of the halogen atom, the boranyl group, and the triflate group.

### Claim 5

An organosilica, comprising a polymer of at least one organosilane expressed by general formula (1):
wherein:
Ar represents any one divalent aromatic organic group selected from the group consisting of a phenylene group, a biphenylylene group, a naphthylene group and a pyridylene group;
R1 represents any one of a hydrogen atom and alkyl groups having 1 to 4 carbon atoms;
R2 to R6, which may be the same or different from each other, each represents any one substituent selected from the group consisting of a hydrogen atom, a methyl group, an ethyl group, a propyl group, a butyl group, an isopropyl group, a pentyl group, a hexyl group, and a cyclohexyl group; and
X represents any one reactive substituent selected from the group consisting of a halogen atom, a magnesium halide, a zinc halide, a stannyl group which may have a substituent, a boranyl group which may have a substituent, and a triflate group.
