N-Funktionalisierte Cyclopentadienid-Anionen; Chloronium- und Bromonium-Cyclopentadienide
摘要:
2,3-Dicyano-1,4-diethoxycarbonylcyclopentadienide anion (3) is N-functionalized by nitration, nitrosation, azo coupling or diazo-group transfer. Phenylbromonium- and phennylchloronium-cyclopentadienes 14 and 15 are synthesized by photolysis of the diazo compound 13 in the appropriate halobenzene.
