Rhodium-Induced Reversible C?C Bond Cleavage: Transformations of Rhodium(III) 22-Alkyl-m-benziporphyrins

The structurally prearranged carbaporphyrins 22-methyl- and 22-ethyl-m-benziporphyrins provide the platform stabilizing aromatic rhodium(III) 22-(μ-methylene-m-benziporphyrin) and rhodium(III) 22-(μ-ethylidene-m-benziporphyrin). An intramolecular conversion facilitated by the m-phenylene reactivity and observed for both aromatic complexes efficiently leads to rhodium(III) 21-(μ-methylene)-21-carbaporphyrin and rhodium(III) 21-(μ-ethylidene)-21-carbaporphyrin. The distinctive macrocyclic environment of rhodium(III) 21-carbaporphyrin created an opportunity to trap unique organometallic transformations of inner core substituents affording the fulvene-like bond pattern or the rearrangement to 21-vinyl substituent. The one-electron reduction of the rhodium(III) carbaporphyrin anion π-radical with a (dxy)2(dxz)2(dyz)2–(P.?) electronic configuration is demonstrated. The further process of reduction of paramagnetic species triggers the ethyl migration from carbon(22) to rhodium(III), affording the diamagnetic rhodium(III) meta-benziporphyrin containing the apically coordinated σ-ethyl ligand providing an example of reversible C(sp2)?C(sp3) bond cleavage.

Syntheses of Dihydropyrenes with Functionality in the Cavity of the ?-Electron Cloud

The cyano group is shown to be a good group for directing ortho lithiation and, with 2,6-dicyanotoluene as starting material, ortho lithiation provides easy access to a variety of 1,2,3-trisubstituted benzene derivatives.The use of such derivatives in the standard thiacyclophane synthesis of dihydropyrenes has provided in good yield trans-15-(4'-butenyl)-16-methyldihydropyrene (14a) and trans-15-(methoxyethyl)-16-methyldihydropyrene (14b), the first examples of dihydropyrenes having functionality within the cavity of the aromatic ?-electron cloud.
