Microwave assisted synthesis of [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazine Derivatives
New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...
متن کامل(E)-3-(2-Hydroxy-5-methylphenylimino)indolin-2-one
In the title compound, C(15)H(12)N(2)O(2), the dihedral angle between the two benzene rings is 83.55 (11)° In the crystal, the molecules are linked by O-H⋯O and N-H⋯O hydrogen bonds.
متن کامل(E)-1-(5-Bromo-2-hydroxyphenyl)-3-[4-(dimethylamino)phenyl]prop-2-en-1-one
In the title compound, C(17)H(16)BrNO(2), the two benzene rings make a dihedral angle of 7.4 (3)°; the hy-droxy group links to the carbonyl group via an intra-molecular O-H⋯O hydrogen bond. In the crystal, weak C-H⋯O inter-actions link the mol-ecules into a supra-molecular chain running along the c axis.
متن کاملThe Crystallographic, Spectroscopic and Theoretical Studies on (E)-2-[((4-fluorophenyl)imino)methyl]-4-nitrophenol and (E)-2-[((3-fluorophenyl)imino)methyl]-4-nitrophenol Compounds
In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...
متن کامل(E)-3-[5-(Diphenylamino)thiophen-2-yl]-1-(pyridin-3-yl)prop-2-en-1-one
In the title compound, C24H18N2OS, the pyridine and the two phenyl rings are oriented at dihedral angles of 10.1 (5), 71.7 (6) and 68.7 (5)°, respectively, to the central thio-phene ring. In the crystal, pairs of weak C-H⋯O hydrogen bonds link inversion-related mol-ecules, forming dimers. The dimers are linked by further weak C-H⋯O hydrogen bonds, forming chains running along the a-axis direction.
