An efficient pyridyl-directed Rh(III)-catalyzed o-carborane B(3)–H acyloxylation is reported. The B(3)–H bond is the most electron-deficient vertex on o-carborane whose functionalization is challenging. The combination of Cu(OH)2 and diverse carboxylic acids provides low cost and abundant acyloxyl sources which could lead to moderate to excellent yields.

吡啶基定向Cp * Rh(III)催化甲硼烷的B(3)–H酰氧基化

报道了一种有效的吡啶基定向的Rh(III)催化的碳硼烷B(3)–H酰氧基化反应。B(3)–H键是碳硼烷上最缺乏电子的顶点,其功能化具有挑战性。Cu(OH)2和各种羧酸的组合提供了低成本和丰富的酰氧基源,可导致中等至极好的收率。
