Part A, Synthesis of new 2-substituted-3-aryl-4(3H)-quinazolinones as potential CNS agents: part B, Reactions of β-diketones with benzophenone in the presence of potassium hydride
… steric constraints in the latter anion. Sodium hydride promoted acylations at the 2-methyl group of methaqualone were achieved in refluxing 1,2-dimethoxyethane (DHE) with ethyl acetate as well as with various nonenolizable esters, such as ethyl trifluoroacetate and substituted benzoate esters. …

ASYMMETRIC REDUCTIONS BY CHIRAL LITHIUM-ALUMINUM HYDRIDE AND POTASSIUM-BOROHYDRIDE REAGENTS
… which was allowed to react with a suspension of potassium hydride in tetrahydrofuran to form a borate hydride {potassium (S,S,S)-triisopropanolamine borate hydride, 3}. Propiophenone was reduced to optically active alcohol in 14% enantiomeric excess (ee) (R) by 3 in THF.</p><p>By reaction of …

A Diverse Array of Synthetic Strategies for Phosphorus Group Transfer Chemistry: From Phosphinidenes to Phosphates
… approach to producing phosphite (HPO₃²⁻) via hydride-mediated reduction of condensed phosphates. Using potassium hydride, a range of inorganic phosphate sources—including pyrophosphate, triphosphate, trimetaphosphate, fluorophosphate, and polyphosphate—were converted to phosphite in moderate …

Novel Metal Amido-Complexes – Syntheses, Reactivity and Asymmetric Catalysis
… In the third section of this thesis a novel potassium-mediated synthesis of 6-aminofulvenes from N-aryl imines is introduced. During the hydrogenation experiments regarding the optimization of the added base, the formation of a by-product was observed, if potassium hydride was utilized as a …
