Three iron(III)-metal-free porphyrin dimers linked covalently with a flexible butoxy chain at the paru position of the two phenyl rings have been prepared and characterized. The hydroxylation of cyclohexane catalyzed by these dimers with molecular oxygen under mild condition has been studied prelimi

## Abstract We have examined the electronic and geometrical effects of the progressive addition of bulky electron‐withdrawing NO~2~ groups at the adjacent __meso__ positions of Fe^III^‐μ‐oxo octaethylporphyrin dimers. The successive addition of mono‐, di‐, tri‐, and tetranitro substituents at the _
