Synthesis of unsymmetrical N-carboranyl NHCs: directing effect of the carborane anion.
The syntheses of unsymmetrical N-heterocyclic carbenes (NHCs) that contain a single N-bound icosahedral carborane anion substituent are reported. Both anionic C-2 and doubly deprotonated dianionic C-2/C-5 NHC lithium complexes are isolated. The latter species is formed selectively, which reveals a surprising directing effect conveyed by icosahedral carborane anion substituents.
متن کاملCarborane radical anions: spectroscopic and electronic properties of a carborane radical anion with a 2n + 3 skeletal electron count.
One-electron reduction of the well-known carborane 1,2-Ph2-1,2-C2B10H10 (1) gives rise to a stable carborane radical anion ([1]-) with a true 2n + 3 cluster electron count; the geometry of ([1]-) features an elongated C...C cage distance but no significant pi-bonding interactions between the cage and the phenyl substituents.
متن کاملHigh yield C-derivatization of weakly coordinating carborane anions.
Unlike the "parent" carborane anion CHB(11)H(11)(-), halogenated carborane anions such as CHB(11)H(5)Br(6)(-) can be readily C-functionalized in high yield and purity, enhancing their utility as weakly coordinating anions.
متن کاملNovel iodinated carboranes: synthesis of the 8-iodo-7,9-dicarba-nido-undecaborate anion and 2-iodo-1,7-dicarba-closo-dodecaborane.
Electrophilic iodination of the 7,9-dicarba-nido-undecaborate anion with molecular iodine in the presence of AlCl3 generated a new carborane anion-8-iodo-7,9-dicarba-nido-undecaborate-in excellent yield. The capping of the new anion with HBCl2 yielded a previously unknown neutral iodinated carborane, 2-iodo-1,7-dicarba-closo-dodecaborane.
متن کاملCrystal structure of 1-butyl-2,3-dimethylimidazolium dicarba-7,8-nido-undecaborate
In the title mol-ecular salt, C9H17N2 (+)·C2H12B9 (-), the carborane cage has a bridging B-H-B bond on the open B3C2 face. The butyl side chain of the cation adopts an extended conformation [C-C-C-C = 179.6 (1)°]. In the crystal, the imidazolium ring is almost coplanar with the open face of the carborane anion. The cations stack in the [010] direction and the dihedral angle between the imidazol...
