Potassium Alkylpentafluorosilicates, Primary Alkyl Radical Precursors in the C-1 Alkylation of Tetrahydroisoquinolines

In this study, we demonstrate that potassium alkylpentafluorosilicates (RSiF5K2) are efficient primary alkyl radical precursors for selective C(sp3)-C(sp3) bond-forming reactions. RSiF5K2 reagents are white, free-flowing solids and are moisture and air stable. This class of reagents enables the direct C-1 alkylation of tetrahydroisoquinolines under mild conditions via single-electron transfer. The broad substrate scope of both alkylpentafluorosilicates and tetrahydroisoquinolines is tolerated in this transformation. Both radical scavenger and EPR capture experiments show that the primary radical is generated by the oxidation of RSiF5K2. A mechanism involving alkyl radical addition to an iminium salt followed by reduction by an amine is proposed.

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.
