Three′s company: The selective α‐arylation and α‐arylative esterification of linear and branched aldehydes is reported for a variety of bromoarenes. The acylation of aryl bromides can be achieved with linear aldehydes (see scheme). All these transformations were performed with a single [(N‐heterocyclic carbene)Pd] catalyst through adjustment of the stoichiometry of the reagents and the appropriate
Three's company:报道了各种溴代芳烃对直链和支链醛的选择性α-芳基化和α-芳基酯化反应。芳基溴化物的酰化可通过线性醛来实现(参见方案)。所有这些转化都是通过调整试剂的化学计量和适当的碱,使用单一的[(N-杂环卡宾)Pd]催化剂进行的。
