Five novel benzimidazole salts (\textbf1}--\textbf5}) having N-phthalimidoethyl and 4-substituted benzyl were synthesized and identified by $^1}$H NMR, $^13}$C NMR, and IR spectroscopic methods and microanalysis. A mixture of the benzimidazole salts (\textbf1}--\textbf5}), Pd(OAc)$_2}$, and K$_2}$CO$_3}$ in DMF-H$_2}$O catalyzed, in high yield, the Suzuki--Miyaura and the Heck--Mizoroki cross-coupling

In this study fourteen novel cobalt (II) or zinc (II) complexes of benzimidazoles were synthesized from the 1-(4-substitutedbenzyl)-1H-benzimidazoles and CoCl2·6H2O or ZnCl2. Cytotoxic activities of novel complexes were investigated against lung cancer cells (A549) and BEAS-2B. Three of the examined compounds (1, 4 and 5) showed high cytotoxic activity against A549. While the IC50 of the cisplatin

nzoic acid (4-PPBAH) ligands originated from in situ transformation of the 4-BICN and 4-PPCN ligands relying on the hydrolysis of cyano to carboxyl groups, coordinating with metal centers to result in diverse metal–organic fragments and linking modes of PMo12 or SiMo12 polyoxoanions. But, the in situ hydrolysis of the cyano group did not occur in the presence of SiW12 and Cu2+ (or Co2+) ions for complexes
