Synthesis and characterization of ester derivatives of stilbene derived from acid derivative (of p-chloro phenyl acetic acid, substitute benzaldehyde, triethyl amine) with methanol and sulphuric acid

Vol. 47

49--55

Two stilbene derivatives have been synthesized in two step process. First step involved synthesis of acid derivative from p- chloro phenyl acetic acid, substituted benzaldehyde and triethyl amine, where as the second step involved synthesis of substituted stilbene derivatives (enoate or esters) through very simple route . These derivatives were characterized by various spectral techniques and were screened for their antimicrobial activities.

Stability of Mn(II) Complexes with Acetic Acid Derivatives

Pedras M., John E.

Polish Journal of Chemistry

2007

Vol. 81, nr 10

1701-1706

Composition and stability constants of Mn(II) complexes with acetic, glycolic (hydroxyacetic), methoxyacetic and phenylacetic acids, glycine (aminoacetic acid), and sarcosine (N-methylglycine) were determined, at a constant ionic strength = 0.1 KNO3 using the potentiometric method at 20 graduate C. Values of stability constants were found by Bjerrum graphical method and also numerically using Martell and Motekaitis program. The following logK1,graph. values of Mn(II) complexes were found: 2.21 for the complex with acetic acid, 2.45with glycolic acid, 2.10 with methoxyacetic acid, 2.48 with phenylacetic acid, 3.10 with glycine and 3.05 with sarcosine.
