| Abstract | ||
| This study concerns with synthesis of new cycloheptatriene compounds substituents with some electron with drawal groups such as triphenyl arsinyl, methoxide, ethoxide, acetate, phenoxide, benzoate, amino, nitro, and benzene sulphonate, and styudy the effects of these groups on the chemical shift for H7, and also investiyated the UV absorption of the synthesized compounds which show clear hyperchromic led to shift the absorption values to red shift, 1H-NMR of these compounds did not show significant chemical shift for proton H7. | ||
