Vinylporphyrins containing one vinyl group at the pyrrole or benzene ring and their complexes with Cu ^2+^ and Zn ^2+^ have been obtained by the Wittig reaction. The compounds obtained were characterized by physicochemical methods. X-ray diffraction analysis of 5-(4-vinylphenyl)-10,15,20-triphenylpo
Chloroquine (CQ) enantiomers were prepared by a novel synthesis starting from either (S)-or (R)-pyroglutamic acid. Light-absorption spectra of CQ and of complexes of ferriprotoporphyrin IX (FP) with CQ were measured in dilute aqueous solutions at pH 7.3 and 11.3. Spectrophotometric titrations at the
