The invention comprises a method for determining the corrosion rate of metals in contact with a liquid system which is capable of causing corrosion of such metals which comprises adding to the liquid system an electrochemically active compound having a reduction potential more positive than the metal in contact with the liquid system and then monitoring the system thus treated with the electrochemically active compound to determine its rate of reduction which is proportional to the corrosion rate of the metal.

A new reagent for the oxidation of hydrazones to diazo compounds is described. N‐Iodo p‐toluenesulfonamide (TsNIK, iodamine‐T) allows the preparation of α‐diazoesters, α‐diazoamides, α‐diazoketones and α‐diazophosphonates in good yield and in high purity after a simple extractive work‐up. α‐Diazoesters were also obtained in high yield from the corresponding ketones through a one‐pot process of hydrazone
