Piperidine, 1-ethyl-: ACTIVE
Anwendungen
VerwendenIn Room temperature phosphorescence of α-bromonaphthalene induced by cyclodextrin in the presence of hexahydropyridine or 1-ethylpiperidine and its application is described. The highest yields of 5-Bromopyrimidine (37%) were obtained by using 1-ethylpiperidine or triethylamine as condensing agent. Tributyltin hydride and 1-ethylpiperidine hypophosphite were mediated intermolecular radical additions to 2, 4, 6-trichlorophenyl vinyl sulfonate.
