A new family of organometallic compounds, organozirconium reagents, are shown to serve as suitable partners in cross-coupling reactions of (activated) secondary alkyl electrophiles. Thus, the first catalytic method for coupling secondary alpha-bromoketones with alkenylmetal reagents has been developed, specifically, a mild, versatile, and stereoconvergent carbon-carbon bond-forming process that generates
一个新的有机金属化合物家族,有机锆试剂,被证明可作为(活化的)仲烷基亲电试剂交叉偶联反应的合适伙伴。因此,开发了第一种将仲 α-溴酮与烯基金属试剂偶联的催化方法,特别是一种温和、通用和立体会聚的碳-碳键形成过程,可生成具有良好对映选择性的潜在不稳定 β, γ-不饱和酮。
