“…Its Cu(II) complex possesses tetrahedrally distorted square planar geometry whereas Co(II), Ni(II) and Zn(II) complexes show distorted tetrahedral geometry and VO(IV) complex shows square pyramidal geometry. 55 The azo-Schiff base 61 forms complexes with VO(IV), Co(II), Ni(II), Cu(II) and Zn(II); octahedral geometry is proposed for all those complexes from their electronic spectra and magnetic susceptibilities. The conductance data indicate non-electrolytic nature of the complexes except the VO(IV) one which is electrolytic in nature.…”

“…The compounds 25 and 1 underwent condensation reaction to form Schiff base 26 in ethanol at room temperature or dry benzene containing 4‐toluenesulfonic acid as catalyst through 1,2‐addition . Condensation followed by 1,4‐addition with solvent was also possible in this case, and the reaction afforded 27 [5,30,31a,b] (Scheme ).…”

4‐Oxo‐4H‐1‐benzopyran‐3‐carboxaldehyde (chromone‐3‐carboxaldehyde or 3‐formylchromone) 1 is an important biologically active compound. It can serve as a precursor in the synthesis of a wide range of heterocyclic systems having chromone moiety, many of which exhibit broad spectrum of biological activities such as anti‐mutagenisity, cytotoxicity, thymidine phosphorylase inhibitor, and anti‐HIV activity. During the last decade, the title compound was studied extensively. The review presents an overall survey of the synthesis, chemical reactivity, and biological activities of 4‐oxo‐4H‐1‐benzopyran‐3‐carboxaldehydes and some of its derivatives.

Throughout human history, bacteria and fungi have caused infections that are difficult to combat. For this reason, countless research groups have developed novel compounds to solve this problem. Thiazole and benzothiazole are present in different structures with interesting biological effects and are used to develop new effective antimicrobial agents. Moreover, nitrogen atoms that are present in this heterocycle allow for coordination with various metals, forming metal complexes that enhance the biological activity of organic ligands that are often used as commercial drugs. This bibliographical review summarizes the copper complexes that use thiazole and benzothiazole as ligands and that report efficient antimicrobial activity against different bacteria and fungi.
