Shishlikova, Maria A. published the artcileDirected Synthesis of Regioisomeric Monoaryl-Substituted Pyridines Containing a Tricyanobutadiene Fragment and Study on Their Optical Properties, Category: isoquinoline, the main research area is tricyanobutadieyl pyridine preparation regioselective optical study; chlorocinnamaldehyde malononitrile dimer heterocyclization; arylmalondialdehyde malononitrile dimer heterocyclization; enaminoketone malononitrile dimer heterocyclization.
A series of regioisomeric monoaryl-substituted pyridines I (Ar = H, Ph, 4-methoxyphenyl, 3,4-dimethoxyphenyl; Ar1 = H, Ph, 4-methoxyphenyl, 3,4-dimethoxyphenyl; Ar2 = H, Ph, 4-methoxyphenyl, 3,4-dimethoxyphenyl) containing a tricyanobutadiene fragment was prepared using modified known and novel developed synthetic approaches. Advantages and limitations of the used methods were discussed. Dependence of the optical absorption and emission characteristics on the position of aromatic substituent was studied. An unusual intramol. charge transfer from malononitrile fragment to the pyridine ring was found, which was consistent with observed exptl. and theor. data.
