Reaction of ethyl diazoacetate with cobalt porphyrins. Part 2

Abstract

The reactions of ethyl diazoacetate with various cobalt complexes of meso-tetraphenylporphyrin are shown to proceed similarly to those of cobalt complexes of octaethylporphyrin, although the products are less stable. In the cobalt octaethylporphyrin series, two examples are provided of the nucleophilic fission of porphyrin nitrogen–carbon bonds with formation of alkylcobalt porphyrin derivatives.
