Abstract

A new porphyrin bearing chloro per-fluoropolyether substituents at the meso positions was prepared in five steps starting from chloro per-fluoropolyether carboxylic acid. Metallation of this porphyrin was accomplished with cobalt and zinc. Both the free base and its complex with zinc are highly soluble in supercritical CO 2 under very mild conditions (40°C and 20 MPa) thus allowing, in principle, homogeneous catalytic processes to be performed in this non-conventional reaction medium.
