We report new, high-yield methodologies for oxidizing Fischer carbenes, particularly hydrazinocarbene complexes. The reagents traditionally used to oxidize Fischer carbenes have failed because of the stability of hydrazinocarbene complexes and the easy oxidation of formed hydrazides in the reaction conditions. The three newly developed methodologies are very mild, fast, efficient, and complementary. Differently functionalized hydrazinocarbene complexes can be oxidized to afford new hydrazides.

Abstract
We report new, high-yield methodologies for oxidizing Fischer carbenes, particularly hydrazinocarbene complexes. The reagents traditionally used to oxidize Fischer carbenes have failed because of the stability of hydrazinocarbene complexes and the easy oxidation of formed hydrazides in the reaction conditions. The three newly developed methodologies are very mild, fast, efficient, and complementary. Differently functionalized hydrazinocarbene complexes can be oxidized to afford new hydrazides.File in questo prodotto:
