The synthesis of three novel unsymmetrical free base, zinc(II) phthalocyanine derivatives obtained from 3,6-di-(thiophen-3-yl)phthalonitrile and 3,6-didecylphthalonitrile are described. The synthesis of novel 3,6-substituted phthalonitriles bearing heteroaromatic derivatives were achieved through Suzuki-coupling reaction by treatment of 3,6-di(trifluoromethanesulfonyloxy)phthalonitriles and heteroaromatic boronic acids. Two of the newly synthesized complexes showed a high efficiency against a model biological substrate, such as N-acetyl-L-tryptophanamide NATA, and shows a high singlet oxygen quantum yield.

The synthesis explored to serve novel functional group extended Anti-microbial bio-active molecules of substituted Aminothiazoles. It reveals from overall available up to date literature feedback of Aminothiazoles, it is difcult to synthesis of substituted biphenyl-2-aminothiazoles from Suzuki coupling reaction of 5-(4-bromophenyl) thiazol-2-amine with substituted Boronic acids in presence of Palladium (II) acetate catalyst and in 5% aqueous Isopropyl alcohol used as a solvent. This is a shortest pathway to synthesis of biphenyl derivatives of Aminothaizoles by Suzuki coupling method.

A concise synthesis of rhodanthpyrone A and B was accomplished via a Suzuki coupling reaction. To find the conditions appropriate to install hydroxyphenyl moieties to the α-pyrone skeleton, a model study was conducted using commercially available boronic acids. It was revealed that the hydroxy moiety of the phenylboronic acids should be concealed when reacted with labile 4-tosyl α-pyrone. Consequently, rhodanthpyrone A and B could be synthesized in high yields by Suzuki reaction using TIPS-protected arylboronic acids. This procedure provided a concise and versatile route for the synthesis of rhodanthpyrones and their 4-aryl substituted α-pyrone analogs.
