ELECTROPHILIC SUBSTITUTION OF N-METHYLOCTAETHYLPORPHYRIN

Nitration of N-methyloctaethylporphyrin (1) takes place at the meso positions adjacent to the N-alkylated pyrrole ring (so-called α- or δ-position).Deuteration with CF3COOD-D2SO4 suggests preferential electrophilic substitution at α- or δ-position on the basis of 1H-nmr investigation.

THE REACTION OF IRON(III) AND COBALT(III) PORPHYRIN PERCHLORATES WITH TRIMETHYLSILYLDIAZOMETHANE

The reaction of perchloratoiron(III) and -cobalt(III) octaethylporphyrins with trimethylsilyldiazomethane afforded N,metal-methano bridged organometalloporphyrins which further reacted with the carbene to give N(21),N(22)- and N(21),N(23)-ethano bridged p

A Molecular receptor based on the 2,3,7,8,12,13,17,18-octaethyl-21,23- dimethylporphyrin for detection of fluoride ions: Synthesis, spectral and complexation properties

2,3,7,8,12,13,17,18-Octaethyl-21-methylporphyrin and 2,3,7,8,12,13,17,18- octaethyl-22,23-dimethylporphyrin monotriflate based on the former were synthesized. Basic and complexing properties of these compounds were studied by the method of spectrophotometric titration in acetonitrile-perchloric acid and acetonitrile-tetrabutylammonium fluoride systems at 298 K. It was established that in the system of acetonitrile-perchloric acid the cationic forms of 2,3,7,8,12,13,17,18-octaethyl-21-methylporphyrin do not form complexes with fluoride ions, whereas 2,3,7, 8,12,13,17,18-octaethyl-22,23-dimethylporphyrin monotriflate forms complexes of 1:1 composition with the fluoride ions. The protonation constant of 2,3,7,8,12,13,17,18-octaethyl-21-methylporphyrin and the stability constant of the complex of 2,3,7,8,12,13,17,18-octaethyl-22,23- dimethylporphyrin with fluoride ions in acetonitrile at the standard temperature were determined.
