已经开发了可靠的合成氧磺酰叠氮化物的方法,并将其应用于由CuI均匀催化的叠氮化物,炔烃和胺的三组分偶联反应,这导致了N-氧磺酰am的形成,收率很高。为了充分评估对该偶联反应的催化活性,有两个配位框架,即无微孔的Cu 2 I 2(PDIN)和有微孔的Cu 2 I 2(BTTP4)(PDIN = 1,4-亚苯基二异烟酸酯,BTTP4 =苯- 1,3,5-三基三异烟酸)是通过简单的一锅反应制备的非均相催化剂。催化结果表明,无孔Cu 2 I 2(PDIN)对三组分偶联反应几乎没有活性,而微孔Cu 2 I 2(BTTP4)是合成N-氧磺酰基am的有效多相催化剂。此外,相对于炔烃基质,多孔Cu 2 I 2(BTTP4)表现出择形性能,并且芳族炔烃优于脂族炔烃。通过一系列物理技术研究了Cu 2 I 2(BTTP4)框架中催化活性位的位置,包括粉末XRD,CO 2 气体吸附,红外光谱,能量色散X射线分析和

unprecedented modulation of submicrohelix versussubmicrostickmorphologies by sonication has been systematically carried out on new propeller-type tri-O-isonicotinoylphloroglucinol. The formation and control of uniform submicrohelix and submicrostickmorphologies show subtle external sonication media effects. The first control of submicrohelicesversussubmicrosticks by sonication without any additive or template

A diverse set of guest molecules template the consistent formation of fifteen iso-structural layered structures containing a pyridine based tripodal ligand, divalent metal ions and anions. These materials have shown a remarkable ability to interconvert from Zn(II) to Cu(II), Cd(II) to Cu(II), Cu(II) to Cd(II) complexes in a SCSC (single crystal-to-single crystal) fashion.

The present invention provides a single crystal of a porous compound, the single crystal being used to produce a crystal structure analysis sample for a compound to be analyzed by contacting the single crystal of the porous compound having a three-dimensional framework and three-dimensionally regularly-arranged pores and/or hollows formed by being divided by the three-dimensional framework with a solution that includes the compound to be analyzed, and arranging molecules of the compound to be analyzed in a regular array in the pores and/or hollows. The single crystal of the porous compound are characterized in that: one side of the single crystal is 10 to 2000 µm; and the single crystal maintains monocrystalline properties even after the single crystal is placed in contact with a solvent that is chemically the same as the solvent of the solution that includes the compound to be analyzed.
