Abstract: 4-(pentafluorosulfanyl)benzenediazonium tetrafluoroborate salt was synthesized and isolated. The pentafluorosulfanyl salt was examined in a wide assortment of reactions to form novel SF5-bearing alkenes, alkynes, and biaryl derivatives using Heck-Matsuda, Sonogashira, and Suzuki coupling protocols. Dediazoniation of the salt furnished the corresponding p-SF5—C6H4X,C6H4OS(O)(CF3)?NSO2CF3, and p-SF5—C6H4-NTf2 derivatives. The azide derivative p-SF5—C6H4N3 entered into click chemistry with phenylacetylenes to furnish the corresponding triazoles. Various SF5-bearing alkenes were synthesized by coupling reactions using a metal catalyst. Fluorodediazoniation selectively furnished the fluoro derivative p-SF5—C6H4F. Homolytic dediazoniation gave the unsymmetrical biaryls, thus demonstrating the broad utility of pentafluorosulfanyl diazonium salts as building blocks of SF5-aromatics that are in high demand in many branches of chemistry including biomedicine and materials chemistry.
Abstract: A crystal form I of (S)-4-hydroxy-2-oxo-1-pyrrolidine acetamide, or named (S)-oxiracetam, is provided, which is characterized by a powder x-ray diffraction pattern that exhibits data of d-values versus the relative intensities as: 7.075(M), 5.355(S), 5.092(S), 4.590(M), 4.325(M), 4.259(S), 4.041(VS), 3.808(M), 3.542(M), 3.445(M), 3.393(M), 2.972(M), 2.914(S). A method for preparing a crystal form I of (S)-oxiracetam is also provided, which includes preparing the crude product and crystallizing A use of the crystal form I of (S)-oxiracetam in the manufacture of a medicament for preventing and treating memory dysfunction is also provided. Accordingly, the crystal form I of (S)-oxiracetam prepared by the method has high purity of more than 99.3% based on the percentages of the mass, with better efficacy than (S)-oxiracetam for preventing or treating memory dysfunction.
