meso-Tetraphenyl meta-benziporphyrins are nonaromatic macrocycles which can be changed to antiaromatic by fusing the core benzene ring with one of the adjacent meso-phenyl groups, as demonstrated here by adopting a premodification method. We used a fluore

Biologically interesting fluorenone, xanthone and anthrone derivatives have been prepared via an intramolecular oxidative acylation process. This novel direct acylation reaction proceeded without the aid of any transition metals, acids or bases, and uses a catalytic amount of a quaternary ammonium salt in the presence of a persulfate oxidant. Initial mechanistic studies have been carried out to elucidate the reaction pathway. The Royal Society of Chemistry 2013.
