Chlorophyll‐ a (Chl‐ a ) was readily converted into Chl‐ d under mild conditions without any enzymes. Treatment of Chl‐ a dissolved in dry tetrahydrofuran (THF) with thiophenol and acetic acid at room temperature successfully produced Chl‐ d in 31% yield. During the acidic oxidation, removal of the central magnesium, pheophytinization, was sufficiently suppressed. This mild pathway can give insights into the yet unidentified Chl‐ d biosynthesis.
