Synthesis of pyrazole (hemi)aminals via the cleavage of saturated aliphatic ether C–O bonds in the presence of ferric halides?
New Journal of Chemistry Pub Date: 2017-01-30 DOI: 10.1039/C6NJ03822K
Abstract
The discovery of reactions utilizing previously considered inert functional groups opens up new paths towards the synthesis of desired products. Solutions of mononuclear ferric–pyrazole complexes react with diethyl ether cleaving a C–O bond to form chelating hemiaminals. Upon exposure to diffuse light, the latter react further to yield mononuclear ferrous products containing chelating aminals.
