Ammonia gas, NH3, is a cheap and widely used industrial feedstock, which has received tremendous research interests in its functionalization. This work reports a breakthrough in catalytic selective cage B(3)-H amination of o-carboranes with NH3 via Ir-catalyzed B-H/N-H dehydrocoupling, offering convenient and efficient access to a series of 3-NH2-o-carborane derivatives in moderate to high isolated

Redox “B”ees: Rational design of a new series of boron‐functionalized NiIII/NiIV–bis(dicarbollide) clusters results in a family of robust and tunable redoxshuttles (see diagram; EDG and EWG denote electron‐donating and ‐withdrawing groups, respectively). This offers a means to rationally control the redox properties in dye‐sensitized solarcells (DSCs), leading to exceptionally high open‐circuit voltages
氧化还原“ B” ee:合理设计一系列新的经硼官能化的Ni III / Ni IV -bis(双碳棒)团簇,产生了一系列坚固且可调的氧化还原梭(见图表; EDG和EWG表示电子给体,-退出小组)。这为合理控制染料敏化太阳能电池(DSC)中的氧化还原特性提供了一种方法,从而导致异常高的开路电压。
