moderate temperature (40 °C) without the involvement of any chromatographic purification. Oxidizing and Lewis acidic properties of molecular I2 have been utilized here. Detailed mechanism has been established based on an isolated intermediate and its single crystal X-ray crystallographic structure.

In this paper, we report the synthesis, structure and photophysical studies of four new complexes of conformationally flexible 6-chloro-4-phenyl-2-(pyridin-2-yl)quinazoline ligand (L) with Zn(ii). The coordinating ability of the ligand and geometrical preferences of the resultant complexes are tuned by varying the anion of the metal salt as confirmed by structural and DFT studies. The choice of the
