Synthetic Applications of N-N Linked Heterocycles. Part 15. A Facile Synthesis of 4-Pyridyl(aryl)amines via the Reaction between 4-Chloro-1-pyridiniopyridinium Salts and Aryl Amines

4-Chloro-1-pyridiniopyridinium salts (7) and (8) react with primary and secondary arylamines to give high yields of isolable 4-aryliminium salts (9) and (10).These are readily fragmented into 4-pyridyl(aryl)amines (11) and (12) in excellent yields on treatment with sodium cyanide or sodium salts of sulphonic acids.The method fails with the more basic aliphatic amines, since these apparently attack the 2-position of the chloropyridinium ring giving products resulting from ring-opening.Mechanisms of the reactions are discussed.

Synthesis of 5-(Substituted Phenyl) 4-Acetyl-2-methylthio-Δ2-1,3,4-thiadiazolines and their Oxidation with Potassium Permanganate

The reaction of aldehyde methylthio(thiocarbonyl)hydrazones (2) with acetic anhydride or acetyl chloride gave 5-(substituted phenyl) 4-acetyl-2-methylthio-Δ2-1,3,4-thiadiazolines (3).Oxidation of compounds (3) with potassium permanganate in ace
