Using pyridine as a solvent, I carried out the di-imide reduction process using K2CO3 and p-tosylhydrazine. the formation of bacteriochlorin was confirmed after the appearance of an absorption peak at 749 nm in UV-vis spectra.

You can check by adding stabilizers like ascorbic acid or BHT.
Conduct synthesis and storage under nitrogen or argon.
Switch solvent to DMSO or DMF and store at low temperatures (0–4°C).
Stabilize with metal ions like Zn²⁺.
Add bulky or electron-donating groups to shield reactive sites.
These can effectively minimize oxidation
