- Microwave-assisted synthesis of phenylpyrimidine derivatives via Suzuki-Miyaura reactions in water
-
An efficient method was developed to prepare biphenylpyrimidine scaffolds via a Suzuki-Miyaura coupling reaction. In this procedure, the products were synthesized under microwave irradiation in water and analogues of biguanidine were employed as ligands.

- Synthesis of oligo(diazaphenyls). Tailor-made fluorescent heteroaromatics and pathways to nanostructures
-
Oligoaza derivatives of biphenyl, terphenyl, quaterphenyl, quinquephenyl, sexiphenyl, septiphenyl, octiphenyl, noviphenyl, deciphenyl and dodeciphenyl and poly(pyrimidinylenephenylene) can be synthesized from readily accessible vinamidinium salts and amidines or N,N,N'- tris(trimethylsilyl)amidines. The fluorescence of these systems can be tuned over a wide spectral range by varying number and positions of N atoms. Oligo(diazaphenyls) are thermally and photochemically stable, are easier to reduce than oligopheny]s, can be dissolved at any rate in strong acids and show strong blue fluorescence in solution as well as in the solid state.

- A NEW AND FACILE SYNTHESIS OF 5-ARYLPYRIMIDINES AND 4-ARYLPYRAZOLES
-
A condensation of 2-aryl-3-(methylthio)acroleins (3a)-(3e), a new masked form of arylmalondialdehydes, with amidines yielded the corresponding 5-arylpyrimidines (4a)-(4k).Similarly, the reaction of 3 with N-substituted hydrazines gave the corresponding 1-
