Robust procedures for two mechanistically distinct C(sp3)-Ge bond formations from alkyl electrophiles and germanium nucleophiles are reported. The germanium reagents were made available as bench-stable solutions by lithium-to-magnesium and lithium-to-zinc transmetalation, resp. The germanium Grignard reagent reacts with various primary and secondary alkyl electrophiles by an ionic nucleophilic displacement. Conversely, the coupling of the corresponding zinc reagent requires a nickel catalyst, which then engages in radical bond formations with primary, secondary, and even tertiary alkyl bromides. Both methods avoid the regioselectivity issue of alkene hydrogermylation and enable the synthesis of a wide range of functionalized alkyl-substituted germanes. In the part of experimental materials, we found many familiar compounds, such as (Bromomethyl)cyclopropane(cas: 7051-34-5Application of 7051-34-5)
(Bromomethyl)cyclopropane(cas: 7051-34-5) is used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.Application of 7051-34-5
