Synthesis of Ketazines from Dinitrogen Coordinated to Tungsten
When treated with a methanol/acetone mixture at 50 deg C, the complex trans- gives acetone azine in moderate yield, although the yield is slightly lower than that from cis-.Under UV irradiation, these dinitrogen complexes produce acetone azine even at room temperature.
Ruthenium(ii)-catalysed direct synthesis of ketazines using secondary alcohols
Direct one-pot synthesis of ketazines from secondary alcohols and hydrazine hydrate catalyzed by a ruthenium pincer complex is reported, which proceeds through O-H bond activation of secondary alcohols via amine-amide metal-ligand cooperation in the catalyst. Remarkably, liberated molecular hydrogen and water are the only byproducts.
Azine synthesis via nitrogen-nitrogen bond formation
Imine anions, generated by reaction of nitriles with organometallic reagents, are dimerized to form symmetrical azines through the use of CuI and t-butyl peroxybenzoate.
