| abstract | 1415825 Difluoropyridines OLIN CORP 26 Feb 1974 8598/74 Heading C2C A method of preparing difluoropyridines and substituted difluoropyridines comprises (a) diazotizing a diaminopyridine compound of the formula wherein each R is independently selected from alkyl of 1 to 4 carbon atoms; nitro; alkoxy of 1 to 4 carbon atoms; and halogen and n is 0 or an integer of 1 to 3; in the presence of hydrogen fluoride and sodium nitrite to form a reaction mixture containing the pyridyl bis-(diazonium fluoride) salt of the diaminopyridine compound and (b) then heating the reaction mixture to decompose the pyridyl bis-(diazonium fluoride) salt to the corresponding difluoropyridine. |
