Background: Cr(III) meso-Tetraphenylporphine Chloride (contains 1-3% chlorin) is a synthetically derived metallophorphyrin specialty chemical manufactured by Frontier Specialty Chemicals containing chromium in the (III) oxidation state. This complex has been used for the construction of an salicylate-selective membrane electrode.1 Cr(III) meso-Tetraphenylporphine Chloride in combination with dicobalt octacarbonyl produces a highly active catalytic species for the carbonylation of epoxides to B-lactones, avoiding the need to handle air sensitive intermediates for the preparation of the Coates catalyst.2 Cr(III) meso-Tetraphenylporphine Chloride was used to polymerize styrene oxide catalytically under various conditions in the presence of bis(triphenylphosphine)iminium chloride.3 Exo-selective epoxidation of norbornene  was accomplished using Cr(III) meso-Tetraphenylporphine Chloride as a catalyst.4 Cr(III) meso-Tetraphenylporphine Chloride catalyzed the  dehydrogenative synthesis of imines from alcohols and amines.5 Cr(III) meso-Tetraphenylporphine Chloride was used to synthesize a selectively functionalized polylactide polymer.6
