In this paper we present the convenient syntheses of seven new phenyl hydrazin derivatives 8 (a-h). For this purpose, acenaphtho [1,2-e]-1,2,4-triazine-9(8H)-thione (3) was prepared, starting from acenaphthylene-1, 2-dione (1) and thiosemicabazide in good yield. The reaction of (3) with benzyl chloride resulted to synthesis of 9-(benzylthio)-acenaphtho[1,2-e]-1,2,4-triazines (5) that reacted wi...

UTAGENESIS in germ cells of Drosophila melanogaster males by 2: 4: 6-tri M (ethyleneimin0)-1 : 3 : 5-triazine (“triazine”) has been proven and investigated by the FAHMY’S (BIRD 1952; FAHMY and BIRD 1953; FAHMY and FAHMY 1953, 1954, 1955) and has also been studied by LUERS (1953). The purposes of the present studies were to test whether triazine, like nitrogen mustard (HERSKOWITZ 1947, 1949, 195...

In this work, the reaction of derivatives benzoic acid containing substituents in aromatic ring (1a-o) with 2-chloro-4,6dimethoxy-1,3,5-triazine (4) presence N-methylmorpholine (6) has been synthesized active triazine esters carboxylic acids (3a-o). These compounds obtained potassium butylate (7) vinyl acetate (2) have formed corresponding (5a-o). The electronic effect substitutor affects on ca...

Ethylene-bridged bis(hydroxylamino-1,3,5-triazine) compounds, that may serve as tetradentate ligands, were synthesized in three steps from 2,4,6-trichloro-1,3,5-triazine. These compounds demonstrate different rotation restrictions around the C(Ar)-N bonds due to their distinctive electronic structure as apparent from their resonative contributors. A dinuclear complex Ti 2(mu-L)2(OiPr)4 (L = bis...

The Mn(II) ion in the title complex, [MnBr(2)(C(18)H(12)N(6))], is five-coordinated in a distorted square-pyramidal geometry by three N atoms of the tridentate 2,4,6-tri-2-pyridyl-1,3,5-triazine (tptz) ligand and two bromide anions. In the crystal, the pyridyl rings coordinated to the Mn atom are inclined slightly to their carrier triazine ring [dihedral angles = 8.0 (3) and 7.5 (3)°], whereas ...

The title compound, C(28)H(27)N(5)O, was synthesized using palladium cross-coupling amination of 3-bromo-5,6-diphenyl-1,2,4-triazine with 2-[(4S)-4-tert-butyl-4,5-dihydro-1,3-oxazol-2-yl]aniline. The oxazoline ring is almost planar, with a maximum atomic deviation of 0.023 (5) Å. The phenyl rings make dihedral angles of 29.0 (1) and 54.6 (1)° with the triazine ring while the benzene ring makes ...

A new series of aliphatic thiourea and various aryl urea incorporating 1,3,5-s-triazine moiety is reported. This series has been obtained by the reaction of cyanuric chloride with thiophene-2-ethyl thiourea 1. Thus, the prepared 2-(thiophene-2ethyl thioureido)-4,6-dichloro-s-triazine 2 has been subsequently treated with morpholine to get 2-(thiophene-2-ethyl thioureido)-4-(morpholino)-6-chloro-...
