was developed, providing various α-cyano ketones, esters, and carboxamides containing a nitrile-bearing all-carbon quaternary center in good to excellent yields under mild reaction conditions. The corresponding reaction mechanism involving in situ generated organozinc reagent and reactivity distinction was elucidated by density functional theory computation.
开发了使用亲电子氰化试剂和锌还原剂对叔烷基溴进行还原性氰化的反应,在温和的反应条件下,提供了多种含氰基全碳四元中心的α-氰基酮,酯和羧酰胺,收率良好。通过密度泛函理论计算,阐明了相应的反应机理,包括原位生成的有机锌试剂和反应性的区别。
