1-Bromo-4-methoxybutane (cas: 4457-67-4) belongs to organobromine compounds. Many of the organo bromine compounds are relatively nonpolar. Bromine is more electronegative than carbon (2.8 vs 2.5) and hence the carbon in a carbon–bromine bond is electrophilic in nature. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Recommanded Product: 1-Bromo-4-methoxybutane

Reductive coupling of activated secondary alkyl halides FG-CHXR1 (FG = phosphinyl, sulfonyl; R1 = Me, Et, PhCH2CH2, C6H13) with chlorosilane ClSiMe2(CH:CH2) mediated by manganese metal afforded secondary alkylsilanes FG-CH(R1)SiMe2(CH:CH2) with high yields. The construction of secondary alkylsilanes is a challenging subject in the synthetic community. The cross-coupling provides a practical solution to address this problem, but it typically relies on organometallic species. Herein, we report an Mn-mediated reductive C(sp3)-Si coupling to synthesize these compounds from alkyl and silyl electrophiles. This approach avoids the requirement for activation of Si-Cl by transition metals and thus allows for the coupling of various common chlorosilanes. The reaction proceeds under mild conditions and shows good functional group compatibility. The method offers access to α-silylated organophosphorus and sulfones with a scope that is complementary to those obtained from the established methods. In the experiment, the researchers used many compounds, for example, 1-Bromo-4-methoxybutane (cas: 4457-67-4Recommanded Product: 1-Bromo-4-methoxybutane).
