The synthesis of titled compounds were achieved in one step using hydroxyl naphthones and substituted cinnamic acids in the presence of a catalytic amount of phosphorus oxychloride. X-ray crystal studies were undertaken for three compounds and the results are presented. Compounds 1 (C22H15F3O3) and 3 (C21H15BrO3) formed a monoclinic crystals while compound 2 (C22H15F3O3) formed a triclinic crystals. The observed space group of these compounds is P21/c and P $$ \bar1} $$ respectively. The 2-substituted compounds showed identical space group and showed a perpendicular arrangements of each of the substituents to the plane of the naphthyl ring. On the contrary, the 1-substituted cinnamoyal compound showed an orthogonal arrangement to naphthyl ring but the acetyl group was almost planar relative to the naphthyl moiety. The characterization of the structures of the compounds was also accomplished using high-resolution NMR spectroscopic techniques. The synthesis of titled compound was achieved in one step using hydroxyl naphthones and substituted cinnamic acids in the presence of a catalytic amount of phosphorus oxychloride. X-ray crystal studies were undertaken for three compounds and the results are presented. Compounds 1 and 3 formed a monoclinic crystal while compound 2 formed a triclinic crystal. The molecular formulae of compounds are as follows: C22H15F3O3 (1 and 2) and C21H15BrO3(3) . The observed space group of these compounds is P21/c and P1 respectively.
