Rearrangement of the CH=C-N,N21′,N22′-Linkage in the Mixed Bis(porphyrin) of Octaethylporphyrin and meso-Tetraphenylporphyrin via the CH-CH-N21,N22,N21′,N22′-Linkage

The CH=C-N,N21′,N22′-linked bis (porphyrin) consisting of an N-(vinyl)octaethylporphyrin moiety and a monoprotonated N21,N22-vinylidene-bridged meso-tetraphenylporphyrin moiety was rearranged to the CH=C-N,N21′,N22′-linked bis(porphyrin) consisting of an N-(vinyl)-meso-tetraphenylporphyrin moiety an...

Description
Summary:The CH=C-N,N21′,N22′-linked bis (porphyrin) consisting of an N-(vinyl)octaethylporphyrin moiety and a monoprotonated N21,N22-vinylidene-bridged meso-tetraphenylporphyrin moiety was rearranged to the CH=C-N,N21′,N22′-linked bis(porphyrin) consisting of an N-(vinyl)-meso-tetraphenylporphyrin moiety and a monoprotonated N21,N22-vinylidene-bridged octaethylporphyrin moiety. The CH-CH-N21,N22,N21′,N22′-linked bis(porphyrin) which is a key intermediate of this rearrangement was identified by X-ray crystallography.
