摘要：

beta-Diketiminate cobalt(I) precursors react with diphenyldiazomethane to give a compound that is shown by Computational studies to be a diazoalkane radical anion antiferromagnetically coupled to a high,spin cobalt-(II) ion: Thermolysis of this complex results in formal N-N cleavage to give a cobalt(II) ketimide complex: Experimental evaluation of the potential steps in the mechanism suggests that free azine is a likely intermediate in this reaction.
