A New Class of Solar Cells: Isomeric Boron Carbide Semiconductors with Fourth Quadrant Conductivity - Volume - Ravi B. Billa, A. N. Caruso, J. I. BrandAuthor: Ravi B. Billa, A. N. Caruso, J. I. Brand. Earl Muetterties established a program aimed at fundamental borane chemistry. Walter Knoth discovered the first polyhedral borane anion, B 10 H 10 =, and also discovered that the borane anions displayed a substitution chemistry similar to that of aromatic hydrocarbons.
Boranes add to one π-bond of an alkyne just as they add to the π-bond of an alkene, so the product is the corresponding alkenyl (vinyl) borane. Alkenylboranes undergo many of the same reactions as alkylboranes. 36 Internal alkynes (e.g., hexyne) react with diborane to give the trialkenylborane (29) in moderate yield, but terminal alkynes (e.g., hexyne) give predominantly the 1,1. This is substantiated by a detailed extended Hückel‐based molecular orbital (MO) study using B 10 H 14 as a model system to represent macropolyhedral boranes with higher fusions. An isolobal equivalent structure, [C 8 H 6 (Ru(CO) 2 Me) 2 ] (17), studied at the B3LYP/LANL2DZ level Cited by: 7.
The formulation of polyhedral boranes for the boron neutron capture therapy of cancer. 19 November Download Type: Adobe PDF The early promise of boron neutron capture therapy as a method for the treatment of cancer has been inhibited by the inherent toxicity associated with therapeutically useful doses of 10B-containing pharmacophores, the need for target-tissue specificity . A polyhedral borane cluster consists essentially of a fused polyhedron including an open decaborane cage fused to a closed dodecaborane cluster wherein borane atoms are not an integral part of the cluster vertices. The polyhedral borane cluster can be contained within a biomolecule for use as a neutron capture reagent. A method of synthesizing the polyhedral borane cluster includes the step of Cited by: 6.

These are the so-called closo boranes, named for their. Part of the Studies in Modern Chemistry book series (SMC) Abstract We saw in Chapter 2 how the bridge bonding in diborane could be described simply in terms of two banana-shaped three-centre electron-pair bonds, although an understanding of the overall distribution of the valence electrons of diborane required a molecular orbital treatment Author: K.
Wade. Muetterties's work on boron hydride clusters led to the work on several polyhedral borane anions such as B 12 H 12 2−. Muetterties was an inventor on some basic findings with the polyhedral borate anions.

The discovery of Na 2 B 10 H 10 in our lab opened a new era in the investigation of BNCT because the polyhedral boranes generally have high boron content, are nontoxic, and are chemically stable. The B n H n 2− (n = 10 and 12) ions have been investigated for BNCT by a variety of investigators during the past 25 years with promising results.
The early promise of boron neutron capture therapy as a method for the treatment of cancer has been inhibited by the inherent toxicity associated with therapeutically useful doses of 10 B-containing pharmacophores, the need for target-tissue specificity and the challenges imposed by biological barriers.
