Copper scorpionate complexes

Although the mononuclear Cu half-sandwich scorpionate complexes (see above) are commonly less active than the Fe ones, copper complexes can be more effective in multinuclear assemblies (including coordination polymers) and our approach for these species concerns their self-assembly synthesis by using a suitable combination of a metal source, a main chelating ligand, a spacer or linker, apart from a pH regulator. A wide discussion on the types of self-assembied multicopper complexes and their use for alkane functionlization is presented in Chapter 3, and only a very brief overall view is outlined here.

So far, the reports on copper and silver scorpionate catalysis are limited to ethyl diazoacetate as the carbenoid precursor, and it is questionable whether these catalysts can be used with other classes of diazo compounds. The reaction of the more stable methyl diazomalonate resulted in the formation of a remarkable O-bound diazo complex, which was thermally stable (Equation (9)).76...
