Abstract:
1. A method of forming a xanthone derivative, the method comprising: reacting a 2-substituted benzaldehyde with a phenol derivative in the presence of a catalyst system including a palladium catalyst and a copper catalyst to form the xanthone derivative; wherein the 2-substituted benzaldehyde has a structure; where R 1 , R 2 , R 3 , and R 4 are, independently, H, an aryl group, an alkyl group, an alkoxy group, a halide group, an amine group, a hydroxyl group, a nitro group, or a cyano group; and where R 5 is F, Cl, Br, I, a nitro group, or an alkoxy group; and wherein the phenol derivative has a structure: where R 5 , R 7 , R 3 , and R 9 are, independently, H, an aryl group, an alkyl group, an alkoxy group, a halide group, an amine group; a hydroxyl group, a nitro group, or a cyano group; and X is O, S, or NH, and wherein the xanthone derivative formed has a structure: where R
