FTIR studies of the CH3CN-BF3 complex in solid Ar, N2, and Xe: Matrix effects on vibrational spectra

FTIR spectra of the four isotopically substituted 1:1 complexes of acetonitrile and boron trifluoride were recorded in Ar, N2 and Xe matrices. In Ar, previously unreported three vibrational modes of the complex were clearly observed. Several si

Reaction of Halogens with Laser-Ablated Boron. Infrared Spectra of BXn (X = F, Cl, Br, I; n = 1, 2, 3) in Solid Argon

BXn (X = F, Cl, Br, I; n = 1, 2, 3) species were produced by the reaction of laser-ablated atomic boron with F2, Cl2, Br2, and I2, trapped in solid argon at 12 +/- 1 K, and characterized by infrared absorption spectroscopy.The relative band intensities observed for BX , BX2, and BX3 species depended on the method of production.Enclosing the boron target inside a tube and codepositing boron atoms with halogen molecules enhanced the primary reaction products BX and BX2, whereas passing the halogen through the tube and coaxially mixing with atomic boron promoted the final reaction product BX3.Very low laser power favored the BX and BX2 radicals over the BX3 molecules.These studies provide further chemical evidence for the intermediate BX2 radicals.

Thermal isomerization of regiospecifically 10B-labeled icosahedral carboranes

Thermal treatment of regiospecifically 10B-enriched (96%) 3-(10B)-1-2-C2nB9H12 and 2-(10B)-1,-7-C2nB9H12 (nB = boron with normal isotopic abundances) followed by 10B and 11B NMR analysis reveal that (1) 3-(10B)-1,2-C2nB9H12 undergoes rearrangements that completely scramble the enriched boron atom, (2) these rearrangements occur at a rate faster than the conversion of 1,2-C2B10H12 to 1,7-C2B10H12, (3) the 1,7-C2B10H12 that is formed does not re-form 1,2-C2B10H12 at a detectable rate, and (4) at temperatures at which 1,2-C2B10H12 forms 1,7-C2B10H12 at a significant rate, the latter undergoes no further rearrangements. The movement of 10B at 350°C in 1,2-C2B10H12 is compared to the movement predicted by various isomerization mechanisms. The mechanism that appears to give the closest agreement involves a 12-vertex nido intermediate. It was found that a number of previously considered mechanisms, including simple exchange between two boron sites, triangular face rotation in an icosahedron, diamond-square-diamond twist, and rotation of pentagonal pyramids, are extensions of the nido intermediate mechanism. The synthesis and thermal rearrangement of 3-F-S-(10B)-1-2-C2nB9H11 demonstrate that independent intramolecular fluorine migration does not occur during rearrangement.
