The synthesis and properties of different types of sydnonimine salts have been investigated. The stability of these salts containing different types of acid components has been examined, and their behaviour towards bases and acids and on catalytic hydrogenation is described. The UV.- and NMR.-spectra of a number of these compounds are given and discussed.
The purification method of an aldehyde compound of the present invention includes a step of neutralizing a reaction solution containing an aldehyde compound by adding water and a base compound to the reaction solution, and a step of distilling the neutralized reaction solution, in which the reaction solution is obtained by reacting a compound represented by the following Formula (a1) or (a2) with hydrogen and carbon monoxide in the presence of a metal compound of groups 8 to 10 and a phosphorus compound, the phosphorus compound is represented by Formula (R

as the oxidant, catalyzed by a ruthenium pincer complex. This unprecedented reaction protocol liberates hydrogen gas and avoids the use of sacrificial oxidants. A wide variety of primaryamines are selectively transformed to carboxylates or ketones in good to high yields. It is noteworthy that mechanistic experiments and DFT calculations indicate that in addition to serving as the oxidant, water also
