silacyclopentanes with a three- or four-substituted stereocenter asymmetrically. Mechanistic studies using hybrid density functional theory suggest a catalytic cycle involving oxidative addition, carbene migratory insertion, and reductive elimination. In addition, roles of the chiral ligands in controlling the reaction enantioselectivity are also elucidated.

A Cu-catalyzed cascade reaction of four-membered silacyclobutanes (SCBs) and thiosulfonates to construct S (Se)-containing organosiliconcompounds was developed. The protocol shows a wide range of substrate scope, high functional group compatibility and mild reaction conditions. New C–S (Se) and Si–O bonds were constructed in one step.
开发了 Cu 催化的四元硅杂环丁烷 (SCB) 和硫代磺酸盐的级联反应以构建含 S (Se) 的有机硅化合物。该协议显示了广泛的底物范围、高官能团相容性和温和的反应条件。一步构建了新的 C-S (Se) 和 Si-O 键。
