Abstract:

The molecular structure and conformational analysis of 2-(((1-phenylethyl)imino)methyl)phenol, as a Schiff base witha chiral atom, has been done by calculation methods. According to our calculations at B3LYP and MP2 levels oftheory, three stable conformers (C1-C3) can be drawn for target molecule. The C1 conformer is the most stable, andrelative stability of C2 and C3 are in the range of 1.20-2.67 kcal/mol, in the gas phase and solutions. Also weconsidered the halogen substitution effects, X=F, Cl, and Br, on the conformation stability at both gas phase andsolution. According to our results, the para halogen substitutions have no significant effect on the relative stability ofthree stable conformers.
