alkylation of α-sulfinyl carbanions can take place under biphasic conditions. These new conditions provide a simple, mild and efficient route to allylated sulfoxides in good yields. The reaction tolerates a wide variety of EWG groups as additional carbanion stabilizing groups such as ester, acetyl, cyano, amide, sulfonyl and sulfinyl functions.
钯催化的 α-亚磺酰基碳负离子的烯丙基烷基化可以在双相条件下发生。这些新条件为烯丙基化亚砜的高产率提供了一种简单、温和且有效的途径。该反应容许多种 EWG 基团作为额外的碳负离子稳定基团,例如酯、乙酰基、氰基、酰胺、磺酰基和亚磺酰基官能团。
