Carborane radical anions: spectroscopic and electronic properties of a carborane radical anion with a 2n + 3 skeletal electron count.
نویسندگان
چکیده
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.

BODIPY functionalized o-carborane dyads for low-energy photosensitization.
A new type of organic dyad that can induce low-energy photosensitization has been developed; electron donor and electron acceptor units are boron dipyrromethene (BODIPY) and ortho-carborane (o-Cb), respectively. The new dyads consist of a V-shaped BODIPY-(o-Cb)-BODIPY molecular array in which two BODIPY units are substituted onto two adjacent carbon atoms of the central o-Cb. In the presence of...
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 کاملThe electronic structures and photophysical properties of platinum complexes with C^N^N ligands: the influence of the carborane substituent.
Carboranes have attracted increasing interest in the scientific community due to their remarkable structures and strong electron-withdrawing abilities. In this article, four platinum complexes [(C^N^N)PtC[triple bond, length as m-dash]CPh](1), [(C^N^N)PtC[triple bond, length as m-dash]C-TPA](2), [(C^N^N)PtC[triple bond, length as m-dash]C-TAB](3), [(C^N^N)PtC[triple bond, length as m-dash]C-CB]...
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.
