Abstract

5,6-bis(4-methylphenyl)-2,3-dihydro-1,2,3,4-tetrazine 2 was synthesized by the dimerization of ethyl p-methylbenzoateformylhydrazone 1 in hydrazinehydrate solution. 2,3-bis(4-methylphenyl)-6,7,14,15 - tetrahydro[1,2,3,4] tetrazino [2,3d][1,8, 4,5] benzodithia-diazecine-10,11-dicarbonitrile 4 was sythesized by cyclization reaction of tetrazine monomer 2 onto 1,2-bis-(2-iodoethylmercapto)-4,5-dicyanobenzene 3. Co(II) and Cu(II) phthalocyanine complexes were prepared by reaction of the dinitrile compound (4) with the chlorides of Co(II), Cu(II), and DMAE at 175 degrees C, 350 W in a microwave oven for 10 min. Zn(II)-phthalocyanine complex was prepared by reaction of the dinitrile compound 4 with the acetate of Zn(II) and DMAE at 175 degrees C, 350 W in a microwave oven for 10 min. The new compounds were characterized by a combination of IR, H-1-NMR, C-13 NMR, UV-vis, elemental analysis, and MS spectral data. (C) 2010 Wiley Periodicals, Inc.
