Destruction of Octa(4-tert-butylphenyl)tetrapyrazinoporphyrazine Under the Influence of Nitrogen-Containing Organic Bases in Dimethylsulfoxide

A study is performed of the state of octa(4-tert-butylphenyl)tetrapyrazinoporphyrazine in dimethyl sulfoxide. It is found that the acid–base interaction of partner molecules creates a time-stable complex with proton transfer. It is shown that adding morpholine, piperidine, n-butylamine, and diethylamine to dimethyl sulfoxide results in destruction of this complex, in contrast to adding pyridine, 2-methylpyridine, tert-butylamine, or tri-n-butylamine. The effect the proton-acceptor ability and the spatial structure of the base have on the decomposition of the tetrapyrazinoporphyrazine macrocycle is considered.
