Ruthenium Carbon-Rich Complexes as Redox Switchable Metal Coupling Units

With the help of EPR spectroscopy, we show that the diamagnetic [Ru(dppe)2(- C≡C - R)2] system sets up a magnetic coupling between two organic radicals R, i.e., two nitronyl nitroxide or two verdazyl units, which is stronger than tha

Kinetic investigation of thermal and photoinduced homolysis of alkylated verdazyls

The on-demand generation of stable organic radicals from the precursors can be considered as an essential challenge for the plethora of applications in various fields of science. In this contribution, we prepared a range of N-(methyl)benzyl derivatives of

The syntheses of 4-arylamino-1,2,3-triazoles and stable 6-sydnonyl verdazyls from sydnone derivatives and their fragments

α-Chloroformylarylhydrazones 1 and α-chloroformylarylhydrazones of sydnonecarbaldehydes 3 have been prepared by a new synthetic route: α-chloroformylarylhydrazines hydrochlorides 2 reacted with corresponding carbonyl compounds. Reactions of compounds 3 with various hydrazines to give 6-sydnonyl-1,2,4,5-tetrazinan-3-ones 7 and/or carbazones 8 were also investigated. By oxidization with lead dioxide, compounds 7 were transformed to stable 6-sydnonyl-3,4-dihydro-3-oxo-1,2,4,5-tetrazin-1(2H)-yl radical derivatives 9 (sydnonyl verdazyls). Furthermore, sydnonecarbaldehydes arylhydrazones 5 through acidic conditions could be transferred to 4-arylamino-1,2,3-triazoles 6 which were also obtained by means of acidic decompositions of 4-formylsydnones 10.

Oxidation of Aldehyde Semicarbazones with Lead Dioxide: Application to the Syntheses of 2-Amino-1,3,4-oxadiazoles and 2,4-Dihydro-1,2,4-triazol-3-ones

The oxidation of aldehyde semicarbazones with lead dioxide in acid media was effected.The 4,4-disubstituted semicarbazones of aromatic aldehydes afford 2-amino-1,3,4-oxadiazole derivatives.The 2,4-disubstituted semicarbazones give 2,4-dihydro-1,2,4-triazo
