- Organic boron luminescent material, preparation method thereof and application
-
The invention discloses an organic boron luminescent material, and belongs to the technical field of organic optoelectronic materials. The organic boron luminescent material is structurally characterized in that two organic boron units are introduced onto phenyl quinoline, B on one organic boron unit and N on adjacent quinoline can form intramolecular coordination, so that the organic boron unit has four-coordination boron properties, and the other organic boron unit has three-coordination boron properties at the adjacent position and meta-position or para-position of the quinoline, so that aPi conjugate organic boron luminescent compound is formed. The organic boron luminescent material can emit strong yellow light in a solid state. A preparation method of the organic boron luminescent material is simple in synthetic step, the prepared organic boron luminescent material can be used for luminescent materials and electron transport materials, a triaryl boron unit in the material and fluorine ions can act, and p-pi conjugation between the B and an adjacent conjugate unit is interrupted, so that the luminescent material can be used for detection of the fluorine ions.

- Copper(I) Oxide-Mediated Cyclization of o-Haloaryl N-Tosylhydrazones: Efficient Synthesis of Indazoles
-
An efficient synthesis of indazoles from readily accessible E/Z mixtures of o-haloaryl N-tosylhydrazones has been developed. The thermo-induced isomerization of N-tosylhydrazones is discussed. A series of valuable indazole derivatives are prepared in good yields, and the method has been successfully applied to the synthesis of the bioactive compounds, lonidamine, AF-2785, axitinib, YC-1 and YD-3.

- Facile synthesis of 1-naphthols through a copper-catalyzed arylation of methyl ketones with o-bromoacetophenones
-
The coupling reactions of simple methyl ketones with o-bromoacetophenones and subsquential cyclization reactions were realized to produce a range of 1-naphthols. These cascade reactions were initiated by a rare Cu-catalyzed arylation reaction of methyl ketones with aromatic bromides.

- A simple, safe and efficient synthesis of Tyrian purple (6,6'-Dibromoindigo)
-
6,6'-Dibromoindigo is a major component of the historic pigment Tyrian purple, arguably the most famous dye of antiquity. Over the last century, chemists have been interested in developing practical syntheses of the compound We describe herein a new, reasonably simple and efficient synthesis of Tyrian purple which opens the way to the production of large quantities of the dye with minimal hazards and at low cost.
