Synthesis of 9-C6H5-3-(π-C5H5)-3,1,2-CoC2B9H10 by cross-coupling reaction of 9-I-3-(π-C5H5)-3,1,2-CoC2B9H10 with C6H5ZnCl catalyzed by palladium complexes
摘要:
The cross-coupling reaction of 9-I-3-(pi-C5H5)-3,1,2-CoC2B9H10 with organozinc compounds catalyzed by palladium complexes was used to synthesize the first representative of B-phenyl-substituted carboranes, 9-C6H5-3-(pi-C5H5)-3,1,2-CoC2B9H10.
A convenient new method is proposed for the synthesis of 9-organo-substituted o- and m-carboranes and 2-organo-substituted p-carborane by the substitution of iodine in 9-iodine-o-, 9-iodine-m-, and 2-iodine-p-carboranes by an organic group from an organomagnesium compound in the presence of catalytic amounts of phosphine complexes of palladium. For the first time the halogen in boron halogen carboranes

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
