was developed, providing various α-cyano ketones, esters, and carboxamides containing a nitrile-bearing all-carbon quaternarycenter in good to excellent yields undermild reaction conditions. The corresponding reaction mechanism involving in situ generated organozinc reagent and reactivity distinction was elucidated by density functional theory computation.
A novel Fe-catalyzed fluorosulfonylation of alkenes with Na2S2O4 and N-fluorobenzenesulfonimide (NFSI) for assembling various lactam-functionalized alkyl sulfonyl fluorides is disclosed. In this reaction, Na2S2O4 acts as both an SO2 source and a reductant. Furthermore, the resulting products can be efficiently transformed into valuable chemicals, including sulfonyl esters and sulfonamides, via the
公开了一种新的Fe催化烯烃与Na 2 S 2 O 4和N-氟苯磺酰亚胺(NFSI)的氟磺酰化反应,用于组装各种内酰胺官能化的烷基磺酰氟。在该反应中,Na 2 S 2 O 4既充当SO 2源又充当还原剂。此外,通过六氟化硫交换(SuFEx)点击反应,所得产品可以有效转化为有价值的化学品,包括磺酰酯和磺酰胺。初步机理研究表明该转化通过分子内自由基环化、SO 2插入、亚硫酸根阴离子形成和氟化进行。
