Article abstract of DOI:10.1246/cl.1983.381

Substitution reactions of N-methyltetraphenylporhinatozinc ethyl and tetraphenylporphinatoaluminium ethyl with hindered phenols such as 2,6-di-t-butyl-4-methylphenol and 2,6-di-t-butyl-4-methoxyphenol are accelerated dramatically by the irradiation with v
