Formation of novel spirochlorin and allylidenechlorin by the reaction of bromovinylporphyrin with tetracyanoethylene

Treatment of bromovinylheptaethylporphyrin 1 with tetracyanoethylene leads to the formation of spirochlorin 2 and allylidenechlorin 3via the initially formed Diels-Alder adduct. The former product 2 is a new class of chlorin and the latter 3 exhibits unusual long-wavelength absorption in the red reg...

Description
Summary:Treatment of bromovinylheptaethylporphyrin 1 with tetracyanoethylene leads to the formation of spirochlorin 2 and allylidenechlorin 3via the initially formed Diels-Alder adduct. The former product 2 is a new class of chlorin and the latter 3 exhibits unusual long-wavelength absorption in the red region of the spectrum. The reaction of bromovinylporphyrin 1 with tetracyanoethylene in dichloroethane afforded spirochlorin 2 and allylidenechlorin 3. [Display omitted]
