Triazolopyridines. 13. Reaction between Triazolopyridinium Ylides and Electrophiles
摘要:
The triazolopyridinium ylides (4) are protonated and react with acylium and nitronium ions at the end of the side chain, giving acyl derivatives (8a, 8b) and dinitro derivatives (10a-10c). The structure of the dinitro compound (10b) is confirmed by X-ray diffraction.
