Lithium and sodium salts of the -carbadodecaborate anion [CBH] have been shown to form stable solid-state electrolytes with excellent ionic conductivity for all-solid-state batteries (ASSB). However, potential commercial application is currently hindered by the difficult, low-yielding, and expensive synthetic pathways. We report a novel and cost-effective method to synthesize the [CBH] anion in a 40% yield from [BH], which can be synthesized using common laboratory reagents. The method avoids the use of expensive and dangerous reagents such as NaH, decaborane, and CFSiMe and shows excellent reproducibility in product yield and purity.
-碳硼十二硼酸根阴离子[CBH]的锂盐和钠盐已被证明可形成稳定的固态电解质，对全固态电池（ASSB）具有优异的离子导电性。然而，目前潜在的商业应用受到合成途径困难、产率低和成本高的阻碍。我们报告了一种新颖且具有成本效益的方法，可从[BH]以40%的产率合成[CBH]阴离子，[BH]可使用常见的实验室试剂合成。该方法避免了使用昂贵且危险的试剂，如NaH、癸硼烷和CFSiMe，并在产品产率和纯度方面显示出出色的可重复性。
