  presence of a phosphine-free platinum catalyst, giving 3-substituted 2-boryl-4-silyl-1-butenes through selective cleavage of the less hindered proximal C–C bond of the cyclopropane ring. The steric bulk of the silyl group of the silylboronic esters was critical for efficient formation of the silaboration products, and i-PrPh2Si–B(pin) was developed as a silylboronic ester of choice.

  1-烷基-2-亚甲基环丙烷在无膦的铂催化剂存在下，在温和条件下与甲硅烷基硼酸酯反应，通过选择性裂解受阻较弱的近端C–生成3-取代的2-硼基-4-甲硅烷基-1-丁烯环丙烷环的C键。甲硅烷基硼酸酯的甲硅烷基的空间体积对于有效形成甲硅烷基化产物至关重要，因此开发了i -PrPh 2 Si–B（pin）作为选择的甲硅烷基硼酸酯。
• Kinetic Resolution of Racemic 1-Alkyl-2-methylenecyclopropanes via Palladium-Catalyzed Silaborative C−C Cleavage

  Kinetic resolution of racemic 1-alkyl-2-methylenecyclopropanes via silaborative C-C cleavage was efficiently catalyzed by a palladium complex bearing a chiral phosphoramidite, affording 2-boryl-3-silylmethyl-1-alkenes as major products with up to 92% ee. Enantioenrichment through parallel kinetic resolution, where the slower reacting enantiomer was converted to the constitutional isomer of the major product, may be involved as the crucial stereodiscriminating step.
