Single-electron transfer (SET) oxidation of ionic hypervalent complexes, in particular alkyltrifluoroborates (Alkyl-BF3–) and alkylbis(catecholato)silicates (Alkyl-Si(cat)2–), have contributed substantially to alkyl radical generation compared to alkali or alk. earth organometallics because of their excellent activity-stability balance. Herein, another proposal is reported by using neutral metalloid compounds, Alkyl-GeMe3, as radical precursors. Alkyl-GeMe3 shows comparable activity to that of Alkyl-BF3– and Alkyl-Si(cat)2– in radical addition reactions. Moreover, Alkyl-GeMe3 is the first successful group 14 tetraalkyl nucleophile in nickel-catalyzed cross-coupling. Meanwhile, the neutral nature of these organogermanes offset the limitation of ionic precursors in purification and derivatization. A preliminary mechanism study suggests that an alkyl radical is generated from a tetraalkylgermane radical cation with the assistance of a nucleophile, which may also result in the development of more non-ionic alkyl radical precursors with a metalloid center. In the experiment, the researchers used many compounds, for example, 2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4Recommanded Product: 68716-49-4).
2-(4-Bromophenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (cas: 68716-49-4) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions. Oxidation of organic compounds generally increases the number of bonds from carbon to oxygen (or another electronegative element, such as a halogen), and it may decrease the number of bonds to hydrogen.Recommanded Product: 68716-49-4
