Switching of aromaticity in fluorene-embedded telluraporphyrins by protonation
Pooja Varak, Md Ashif Ali, Bharti Yadav, Mangalampalli RavikanthTwo nonaromatic fluorene-embedded telluraporphyrinoids were synthesized by condensing telluratripyrrane with fluorene diols under acid catalysis, followed by DDQ oxidation. Protonation switches the macrocycles from nonaromatic to aromatic.
