The benzimidazole derivative Schiff bases and their copper(II) (Cu(II)) mixed-polypyridyl complexes (1-4) have been synthesized and characterized by the spectral and analytical techniques. DNA binding/cleavage studies indicate a stronger binding capability for the complex 4 which is confirmed by the absorbance, viscometric and gel-electrophoresis studies. The photocleavage of plasmid pBR322 DNA reveals

Highlights on the development of ferrocene biochemistry in Russia since the 1950s are given. Here, avoiding high-toxic precursors, ferrocene-based imidazoles and benzimidazoles (16 compounds) were synthesized in good to high yields via the reaction of the α-(hydroxy)alkyl ferrocenes with modified heterocycles using oxalylchloride to activate imidazole system. Mild conditions (room temperature, chloroform
