Influence of aromatic substituents on the synthesis of schiff bases derived from trans-(R,R)-diaminocyclohexane: a spectrophotometric and dft b3lyp study

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry
In this work, the synthesis of Schiff bases derived from trans-(R,R)-diaminocyclohexane by microwave irradiation (MW) is presented. The reaction yields varied between 31% and 69%, being influenced by the electronic nature of the substituents (H, Cl, Br ...

Substituent Effects in Thiophenes

Croatica Chemica Acta, 1995
He I and He II photoelectron spectra (UPS) of 2-acetyl and 2-cyano thiophene have been measured. The electronic strucutre of the title compounds and, in particular, the effect of substituents on the thiophene % orbitals is discussed on the basis of band widths, He I/He II intensities and semi-empirical MO calculations.
