Herein, we report a AgF-mediated regio- and stereoselective acetoxyselenylation of terminal/internal alkynes from iodobenzene dicarboxylate [PhI(OCOR)₂] and diorganyl diselenides via multiple-site functionalization to afford β-selenyl enol esters in good yields. Alkynes derived from bioactive molecules, such as l(−)-borneol, l-menthol, and acyne oxalate, are also suitable for this transformation and afford the expected compounds.

银介导的炔烃乙酰氧基硒化：对双功能烯烃的温和立体选择性访问


在此，我们报道了 AgF 介导的碘苯二羧酸盐 [PhI（OCOR）₂] 和二元烷基二硒化物的末端/内部炔烃的区域选择性和立体选择性乙酰硒化，通过多位点官能化得到 β-硒烯醇酯的良好产率。源自生物活性分子的炔烃，如 l（−）-冰片、l-薄荷醇和草酸盐，也适用于这种转化，并提供预期的化合物。
