Abstract Quinazolines are biologically potent heterocyclic compounds; however, their synthesis poses high challenges. In this present study, we have developed an inexpensive cobalt metal‐catalyzed acceptorless dehydrogenative pathway for the sequential of alkenylated quinazolines from benzhydrol via dehydrogenation, cyclization, and subsequent sp 3 C−H functionalization. This transformation holds potential owing to its commercially available key starting materials, good functional tolerance, moderate reaction conditions, environmental friendliness, applicability gram‐scale synthesis. Furthermore, synthetic utility synthesized derivatives has been explored through various reactions, including reduction, halogenation, methoxylation, Michael addition, spiro cyclization. Additionally, photophysical properties indicate that nitrogen atom readily undergoes a reversible protonation, leading significant changes in colour. characteristic presents opportunity creation pH sensors with colourimetric capabilities.

In the frame of a coordination chemistry study on hybrid bis(N-heterocyclic carbene)-bis(phenolate) ligands (L), synthesis novel Fe(III), Cr(III) and Ni(II) complexes is reported. The Fe(III) are obtained starting from their acetylacetonates [M(acac)3] (M = Fe or Cr, acac acetylacetonate), characterized by general formula [M(H2L)(acac)2]Br (2, M 3, Cr), in which only phenolate donors ligand coordinated to metal center.
