A palladium‐catalyzed carbonylative approach for the direct conversion of (hetero)aryl bromides into their α,α‐bis(trifluoromethyl)carbinols is described, and it employs only stoichiometric amounts of carbon monoxide and trifluoromethyltrimethylsilane. In addition, aryl fluorosulfates proved highly compatible with these reaction conditions. The method is tolerant of a diverse set of functional groups
描述了一种钯催化的羰基化方法,可将(杂)芳基溴化物直接转化为它们的α,α-双(三氟甲基)甲醇,仅使用化学计量的一氧化碳和三氟甲基三甲基硅烷。另外,已证明氟代芳基硫酸盐与这些反应条件高度相容。该方法可耐受多种官能团,并且适用于后期碳同位素标记。
