A New Method for the Synthesis of Cobalt Complex of Tetra-2,3-(5-tert-butyl-pyrazino) porphyrazine

Abstract A two-step synthesis of cobalt complex of tetra-2,3-(5- tert -butyl-pyrazino) porphyrazine as porphyrazine derivatives carrying six-membered pyrazine rings annulated at the periphery of the tetrapyrrolic macrocycle was described starting from 3,3-dimethyl-2-butanone, selenium dioxide, 2,3-d...

Summary:Abstract A two-step synthesis of cobalt complex of tetra-2,3-(5- tert -butyl-pyrazino) porphyrazine as porphyrazine derivatives carrying six-membered pyrazine rings annulated at the periphery of the tetrapyrrolic macrocycle was described starting from 3,3-dimethyl-2-butanone, selenium dioxide, 2,3-diaminomaleonitrile, metal salts, and urea. In comparison with the previously reported multistep procedure, this new multicomponent protocol for the preparation of synthetically, biologically, and technologically relevant tetra-2,3-(5- tert -butyl-pyrazino) porphyrazine includes some important aspects like the fast and simple reaction, easy workup procedure, and high atom economy.
