Abstract: The possibility of improving the detection of 1,1-dimethylhydrazine (unsymmetrical dimethylhydrazine, UDMH) by HPLC-SPD under preliminary derivatization with 2-nitrobenzaldehyde (2NBA) and 4?nitrobenzaldehyde (4NBA) in water with micellar cataly

- Synthesis of o -(dimethylamino)aryl ketones, acridones, acridinium salts, and 1 H -indazoles by the reaction of hydrazones and arynes
-
A novel, efficient route to biologically and pharmaceutically important o-(dimethylamino)aryl ketones, acridones, acridinium salts, and 1H-indazoles has been developed starting from readily available hydrazones of aldehydes and o-(trimethylsilyl)aryl triflates. The reaction proceeds through arynes under mild conditions, tolerates a wide range of functional groups, and provides the final products in good to excellent yields.

- From aldehydes to nitriles, a general and high yielding transformation using HOF·CH3CN complex
-
N,N-Dimethylhydrazones of aldehydes undergo a rapid oxidative cleavage to form nitriles in very high yields on reaction with HOF·CH3CN under mild conditions. The reaction is chemoselective and proceeds rapidly without racemization. The nitriles were resistant to further oxidation, even when a large excess of the reagent was employed.
