Benzimidazole-based boranils were designed and synthesized in order to assess the influence of halogen substituents on their optoelectronic properties. All compounds are photoluminescent in solution and solid state. Compared to the free ligands, the

A series of similar synthons highlights the difficulty in predicting the crystal packing of small molecules, and the formation of halogen bonds in the solid state. Small modifications, such as in peripheral groups or in the nature of halogen substitu

Two syntheses of 3-aroylflavones have been established. In the first synthesis the use of microwave irradiation led to an improvement in the yields of both the Knoevenagel condensation of β-diketones with aldehydes to afford 3-aroylflavanones and of
