A novel direct arylation of pyridine N-oxides with arylboronic acids through C-H functionalization has been developed. This new reaction is performed at room temperature using catalytic silver(I) nitrate in the presence of potassium persulfate and give 2-

Two catalytic protocols of the oxidative C-C bond formation have been developed on the basis of the C-H bond activation of pyridine N-oxides. Pd-catalyzed alkenylation of the N-oxides proceeds with excellent regio-, stereo-, and chemoselectivity, and the

The reactions of the monoxides of propylpyrazine and phenylpyrazine with phosphoryl chloride or acetic anhydride were investigated.Except in the case of the reaction of 2-propylpyrazine 1-oxide with acetic anhydride, chlorination or acetoxylation occurred
DECHLORINATION OF SOME CHLOROPYRAZINES AND THEIR N-OXIDES

, p. 1325 - 1328 (2007/10/02)
By heating with sodium formate and tetrakis(triphenylphosphine)palladium, chloropyrazines were converted to the parent pyrazines in satisfactory yields.The chlorine atoms of chloropyrazine N-oxides could also be removed, leaving the N-O group.
