Exploratory studies of the mechanism of 1,3 sigmatropic ring expansion reactions

Creator:: James, Corinne Patricia
Abstract:: The potassium salts of certain 1-vinylcycloalk-3-en-l-ols have been found to undergo sigmatropic ring expansion rearrangements in HMPA. Preliminary investigations of several benzo-substituted medium ring systems were undertaken in order to determine which of these was best suited for further study. A synthetic sequence leading to the formation of 5-methy1-6-viny1-7,8,9,10-tetrahydro-6-benzocyclo-octenol, which...

Infrared spectra and geometry of matrix isolated rare-earth and IIIB metal fluorides

Creator:: Wesley, Robert Dee
Abstract:: The infrared absorption spectra (40-800 cm⁻¹) of the trifluorides of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Tb, Ho, Er, Tm, and Yb isolated in solid argon, krypton and nitrogen matrices have been obtained. For PrF₃ the symmetric and asymmetric stretching modes were observed; PrF₃ is accordingly assigned a...

Synthesis of substituted cyclooctatetraenide dianions ; Cycloheptadienyl complexes of the ḏ- and f̲-transistion elements ; Reactions of cyclohexanone with metal vapors

Creator:: Miller, Jeffrey Templeton
Abstract:: I. Lithium alkyl and aryl monosubstituted cyclooctatetraenide dianions (Li₂ C₈H₇-R; R = methyl, n- butyl, sec- butyl, tert- butyl, phenyl and benzyl) were synthesized by the reaction of the appropriate organolithium reagent with cyclooctatetraene in diethyl ether or tetrahydrofuran. The reaction occurred cleanly and with good yield of lithium monosubstituted...

Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:: Seitz, Earl Philip
Abstract:: The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...

Designing Dielectric Materials through Complex Metal Oxides

Creator:: Nikkel, Jason W.
Abstract:: This dissertation demonstrated that the electrical properties of complex oxide-based perovskite materials could be controlled through the careful modification of both material composition and structure. This was first shown through the modification of lead zirconate titanate (Pb(Zr0.52Ti0.48)O3, PZT) solid solutions with bismuth indate (BiInO3, BI) where the relative stability of...
