Synthesis and antimicrobial activity of 3,4-bis(arylthio)maleimides

A series of 3,4-bis(arylthio)maleimides were synthesized and their antimicrobial activity was evaluated against Gram-positive and Gram-negative bacteria, including multidrug resistant (MDR) strains and some fungi. Most compounds turned out to be highly ac

Diphenylarsinoderivatives of Maleic Acid Anhydride and Related Compounds. Crystal and Molecular Structure of 2,3-Bis(diphenylstibino)maleic Acid Anhydride

The unusual properties of bis(diphenylphosphino)maleic anhydride and similar ditertiary phosphines has prompted the synthesis of analogous arsines and stibines.Bis(diphenylarsino)maleic anhydride, -maleic thioanhydride and -N-methyl maleic imide, bis(diphenylstibino)maleic anhydride (5) and -maleic thioanhydride are obtained as crystalline yellow or red compounds by the reaction of the corresponding 2,3-dichloromaleic acid derivatives with diphenyl(trimethylsilyl)arsine and -stibine resp.The uv/vis spectra and characteristic i.r. bands of selected compounds are given and compared with those of the corresponding phosphines.The strong shift of νC=C to lower wavenumbers observed in all compounds has caused the determination of crystal and molecular structure of 5 by x-ray diffraction.Bond distances and angles are given.The complex formation of the new diarsine ligands has been examined by the preparation of Ni-, Cr- and Mo-carbonyl derivatives.As the first organylsulfane substituted maleic acid derivatives bis(phenylthio)maleic thioanhydride, -N-methyl-maleic imide and -maleic acid dimethylester are synthesized and described. - Keywords: Bis(diphenylarsino)maleic acid, derivatives; Bis(diphenylstibino)maleic anhydride, synthesis, crystal structure; Bis(phenylthio)maleic acid, derivatives; Maleic acid derivatives, synthesis, molecular structure
