- W2080677010 abstract "Die Natriumhydrid-katalysierte Methyljodid-Alkylierung von 2,6-Lutidin-Methojodid (1a) fuhrt in hoherer Ausbeute zum 2-tert.-Butyl-6-isopropyl-1-methyl-pyridiniumsalz (1e) als die Quaternisierung des entsprechenden Pyridins 2e mit Fluorsulfonsauremethylester. Uber die Darstellung der sterisch gehinderten 2,6-dialkylierten Pyridiniumsalze 1b–1e wird berichtet.Steric Hindered Pyridinium Salts, I Base Catalysed C-Alkylation of 2,6-Lutidine MethiodideSodium hydride catalysed alkylation of 1,2,3-trimethylpyridinium iodide (1a) with methyl iodide leads to the pyridinium salt 1e with much higher yield than the quaternisation of the pyridine 2e with methyl fluorosulfonate. The preparation of the hindered pyridinium salts 1b–1e is reported." @default.
