Abstract:

A series of eight l-substituted-2,3,4,5-tetraphenyl-2,4-cyclopentadien-l-ols were efficiently synthesized by the addition of the appropriate organometallic reagent to tetracyclone. It was determined that the steric and electronic nature of the migrating groups played a predictable role in the [l,5]-sigmatropic rearrangement of these compounds. Electron donating groups increased the rate of migration whereas electron withdrawing substituents were responsible for slowing the migration. Likewise, smaller groups accelerated the rate while bulky groups deterred the migration. Consequently, the expe

Astronomical and cosmological observations reveal that the majority of the matter in our universe is made of an unknown, non-luminous substance called dark matter. Many experimental attempts are underway to directly detect particle dark matter, which is very difficult to measure due to the expected low interaction rate with normal matter. DEAP-3600 is a direct dark matter search experiment located two kilometres underground at SNOLAB, in Sudbury, Ontario. DEAP-3600 will make use of liquid argon as the detector material, which scintillates as charged particles pass through. The work presented h

Recent studies show that carbaporphyrin has distinct physical and chemical properties comparing to a regular porphyrin. Importantly, the carbaporphyrin has an internal carbon which can be used to form organometallic metal-carbon bond. The members of the carbaporphyrin family are continuously increasing. Recently we have synthesized novel core-modified benziporphyrin from the condensation of 1,4-bis(α-hydroxyl-benzyl)-benzene with 5,10-ditolyl-16-thia- 5,10,15,17-tetra-hydrotripyr

Various compounds were studied with solid-state 119Sn and 31P NMR spectroscopy and quantum chemical calculations. Connections were made between the shielding tensors and the geometric and electronic structures of the molecules. First, the 119Sn chemical shielding anisotropy of various para substituted tetraaryl tin compounds was shown to be dependent on the tilt angle of the phenyl rings. Tetrakis(o-tolyl) tin did not have the shielding anisotropy predicted by the tilt angle of the rings.
