Efficient Preparation of Pyridinyl-1,2,4-Triazines via Telescoped Condensation with Diversely Functionalized 1,2-Dicarbonyls

The development of materials for efficient chemoselective extraction of minor actinides remains at the forefront of research efforts in the area of separation science. Lewis basic complexants derived from nitrogen-donor scaffolds are often employed in this area due to favorable complexation with the transuranic element americium. In the present work an efficient procedure for the preparation of eight useful 3-pyridin-2-yl-1,2,4-triazines (2 novel) is demonstrated via telescoped condensation with the requisite 1,2-dicarbonyl in two-pots without additives, differentially extractive work-up procedures, or recrystallization. Additional efforts in this area have demonstrated the utility of polar aprotic solvents for the preparation of nine functionalized pyridinyl-2,6-bis-1,2,4-triazines (4 novel) directly from the requisite 2,6-pyridine dicarbonitrile in 49–99% yield over four total steps. The streamlined preparation of these important materials and detailed synthetic procedures is reported herein.

Organic Compound, Benzoxazole Derivative, and Light-Emitting Element, light-Emitting Device, and Electronic Device Using the Benzoxazole Derivative

Novel benzoxazole derivatives are provided to reduce driving voltage of light-emitting elements, and to reduce power consumption of light-emitting elements, light-emitting devices, and electronic devices. A benzoxazole derivative represented by the general formula (G1) is provided. Since the benzoxazole derivative represented by the general formula (G1) has an electron-injecting property, the benzoxazole derivative can be suitably used for light-emitting elements, light-emitting devices, and electronic devices.
