Creator:: Leonard, Mary E.
Abstract:: Iodine-129 is a key risk driver at sites where nuclear materials have been fabricated or processed, and it is a predominant isotope of concern in long-term waste storage strategies. I-129 exists primarily as iodate in the subsurface at the Hanford Site in south-central Washington State. Between 15 and 40% of...

A stereochemically controlled approach to the morphine alkaloids: racemization of 8,9-benzo-4,5-dihydro-6,7-pyrido[4,3-d] oxanin-3(2H)-ones

Creator:: Runyan, Mark T.
Abstract:: A method for the control of absolute stereochemistry in morphine syntheses has been demonstrated by the resolution and efficient racemization of the advanced morphine precursor , 9-methoxy-3-methyl-5,6-dihydro-3H-benzofuro[3,2-e]isoquinoline- 7(7aH)-one, I. This was accomplished by the facile coversion of optically resolved I to its ring opened form, 5,6,7,8-tetrahydro-10-methoxy-3-methyl-7-oxo[1]benzoxonino[ 6,7-c]pyridinium tosylate, II, (Equation...

Intercalation, exfoliation, and nanocomposites of layered inorganic compounds

Creator:: Sukpirom, Nipaka
Abstract:: The melt intercalation of poly(ethylene oxide) (PEO) between layers of MoO₃ and MPS3 (M=Mn,Cd) is obtained by heating the ground mixture and LiₓMoO₃, KₓMn₁-ₓ/₂PS₃, or KCd₁-ₓ/₂PS₃. The products are characterized by powder X-ray diffraction (XRD). Below the melting temperature of PEO (66 °C), intercalation rates and yields are low. By...

Direct atom transfer vs. ring expansion in reaction of rhenium oxo complexes with cyclooctene epoxides and episulfides

Creator:: Khownium, Kriangsak
Abstract:: The rhenium (V) complex Tp'ReO₂ (Tp' = hydrido-tris-(3,5- dimethylpyrazolyl)borate), generated in situ from PPh₃ reduction of Tp'Re0₃, reacts with small ring heterocycles such as epoxides and episulf ides. The strained trans-cyclooctene ring provides an unusual thermodynamic bias against direct atom transfer, but trans-cyclooctene oxide still produces substantial amounts of trans-cyclooctene....
