Synthesis of Some New Heterocyclic Compounds with Potential Biological Activity

A series of new 2-arylimino-3-aryl-5-[5?-(3,4-dichlorophenyl)-2?-furylidene]-4-thiazolidinones (3a-l) have been synthesised by the condensation of 5-(3,4-dichlorophenyl)-2-furaldehyde 1 with 2-arylimino-3-aryl-5H-4-thiazolidinones 2 in glacial acetic acid. The physical and spectral data of the synthesised compounds are determined. The synthesised compounds have been screened for their in vitro ...

Isomerism in the Chemistry of Organogermanium Compounds (Part II)

The organogermanium chemistry covers huge fields, as shown by a survey covering the crystallographic and structural data of over four hundred and fifty examples. Over 10 percent of those compounds exist as distortion isomers (around 97 %) and ligand isomers (around 3 %). These are discussed in term of coordination around the Ge(II), Ge(IV) and Ge2 +3 atoms, and correlations are drawn between do...

An Efficient Method for Correlation of Vapor Pressure of Gaseous Compounds Containing C-H-O

Prediction of available vapor pressure data in the case of compounds containing C-H-O led to derivations and recommendations of standard equations for this property. The accuracy of vapor pressure estimations is essential to use as a basis to calculate acentric factor, thermal and equilibrium properties. In this study, according to the previous work, an accurate equation to estimate vapor press...

Preparation and Reactions of Heterocyclic Compounds II

Commercial preparation of furan proceeds by way of the aldehyde, furfural, which in turn is generated from pentose containing raw materials like corncobs, as shown in the uppermost equation below. Similar preparations of pyrrole and thiophene are depicted in the second row equations. Equation 1 in the third row illustrates a general preparation of substituted furans, pyrroles and thiophenes fro...
