Usage

General Description

(3-Phenylpropyl)methyldichlorosilane is a chemical compound with the formula C11H15Cl2Si. It is a colorless liquid that is used in the synthesis of other organic silicon compounds and as a reagent in organic chemical reactions. (3-PHENYLPROPYL)METHYLDICHLOROSILANE is often used as a crosslinking agent in the production of silicone rubber and as a precursor to functionalized silanes. It is also used as a coupling agent in the production of adhesives, sealants, and coatings. Additionally, (3-Phenylpropyl)methyldichlorosilane has potential applications in the pharmaceutical and agricultural industries. However, it is important to handle this chemical with caution, as it is hazardous if not properly handled and can cause irritation to the skin, eyes, and respiratory system upon contact or inhalation.

Effect of the substituents at the silicon of (ω-chloroalkyl)silanes on the alkylation to benzene

(ω-Chloroalkyl)silanes [Cl3-mMemSi(CH2)n-Cl: m=0-3, n=1-3] underwent Friedel-Crafts alkylation with benzene in the presence of aluminum chloride to give alkylated products. Such alkylation reactions took place at temperatures ranging from room temperature (m=0-1, n=2, 3; m=3, n=1) to 80 (m=1, 2; n=1) and 200°C (m=0; n=1), depending on the substituent(s) of the silicon and the alkylene-chain spacer between the silicon and C-Cl bond of (ω-chloroalkyl)silanes. In the alkylation to benzene, the reactivities of (ω-chloroalkyl)silanes increase as the number (m) of methyl-group(s) at the silicon and the alkylene length between the silicon and C-Cl bond increases. While decomposition of alkylation products was observed at two more methyl groups substituted at silicon in the cases of (chloromethyl)silanes such as (chloromethyl)dimethylchlorosilane and (chloromethyl)trimethylsilane. The reaction with (chloromethyl)trimethylsilane occurred at room temperature to give trimethylchlorosilane, toluene and xylene via a decomposition reaction of the products. No (trimethylsilylmethyl)benzene was formed. In the alkylation to benzene, the reactivity of (ω-chloroalkyl)silanes decreases in the following order: m=3>2>1>0; n=3>2?1. The results are consistent with the stability of the carbocation generated by the complexation of (ω-chloroalkyl)silanes with aluminum chloride.
