A tandem decarboxylation/Diels–Alder reaction of 5-amino-1-phenyl-4-pyrazolecarboxylic acid with 1,3,5-triazines
摘要:
A tandem decarboxylation/Diels-Alder reaction of 5-amino-1-phenyl-4-pyrazolecarboxylic acid with various 1,3,5-triazines was reported. The dienophile, 5-amino-1-phenylpyrazole, was generated in situ via decarboxylation and immediately trapped by 1,3,5-triazines leading to 4,6-disubstituted 1-phenylpyrazolo[3,4-d]pyrimidines in one step.

methods from triazine 1a and various alcohols, ethanethiol, and amines. Lowest unoccupied molecular orbital (LUMO) energy and solubility for these 1,3,5-triazines were determined to assess their potential as azadienes in inverse-electron-demand Diels–Alderreactions (IDA). The thioester 8 showed less LUMO energy and more solubility than triazine 1, suggesting that it may be a better azadiene to study
The present invention relates to metal complexes and to electronic devices, especially organic electroluminescent devices, comprising these metal complexes.
