XeO3 adducts of pyridine, 4-dimethylaminopyridine, and their pyridinium salts

Journal of fluorine chemistry, 2018
Xenon trioxide (XeO3), a highly shock-sensitive detonator, forms adducts with the N-bases, pyridine and 4-dimethylaminopyridine (4-DMAP). The reactions of pyridine and 4-DMAP with XeO3 in rigorously dried CH3CN and in CH3CN that had not been dried ...

Oxidative Diphosphonylation of 1,4-Dihydropyridines and Pyridinium Salts

Organic Letters, 2000
An oxidative double phosphonylation of dihydropyridines 1 and pyridinium salts 2 is achieved through the use of dialkyl phosphites, DDQ, and triethylamine. Acceptable to good yields of 2, 6-diphosphonylated-1,2-dihydropyridines 3 are obtained in a one-pot reaction involving tandem nucleophilic addition/oxidation processes.
