Abstract

1-Amino-5-benzoil-4-fenil-1H-pirimidin-2-on (1) / -tiyon (2) bileşiklerinin ayrı ayrı, 135 o C de etüvde, fenilizotiyosiyanat ile direk olarak 2 saat ısıtılmasıyla 2,8-dibenzoil-3,9-difenildipirimido[2,3-b:2’,3’e] [1,2,4,5] tetrazin (4) bileşiği elde edildi. (4) Bileşiğinin yapısı elementel analiz, IR, 1 H-NMR ve 13C-NMR spektrumları yardımıyla aydınlatıldı.

Keywords

THE REACTIONS OF DIMERYZATION WİTH 1-AMINO-5-BENZOYL-4-PHENYL-1H-PYRIMIDINE- 2-ONE/-THIONE

Abstract

2,8-Dibenzoyl-3,9-diphenyldipyrimido[2,3-b:2’,3’e][1,2,4,5] tetrazine (4) was synthesized via dimerization from the thermolysis of (1) or (2) at 135 oC for 2h with alarge excess of phenylisotiyocyanate. Structural confirmation of (4) was based on elemental analiyses, IR, 1 H-NMR and 13C-NMR spectroscopic data.

Keywords

Isothiocyanate, pyrimidine, amine, tetrazine
