Konyukhova, T. M.; Abramenko, P. I.; Kurkina, L. G. published the artcile< Indolomonomethinecyanines, their spectral and polarographic properties>, Recommanded Product: (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is indolocyanine monomethine spectra polarog; substituent effect polarog reduction potential.
Twelve indolomonomethinecyanies (I; R = H, Ph; R1 = H, Me; R2 = H, CO2H, CO2Et; R3 = H, Cl, NO2, CO2H) were prepared by condensation of 1-methyl-3-formylindoles with indoles unsubstituted in the 3 position in MeNO2 in the presence of HBr. For R = H, R3 has little effect on the position of the absorption maximum; introduction of R = Ph causes a hypsochromic shift due to steric hindrance. All the I exhibit a low polarog. reduction potential, which is lower for R = Ph than for R = H.
