In the title compound, C(17)H(21)N(5)O(3), the dihedral angle between the triazine and the phenyl ring is 80.31 (11)°. One of the morpholine rings is disordered over two orientations with site occupancies of 0.762 (10) and 0.238 (10). Both morpholine rings in the mol-ecule adopt chair conformations.

Triazine herbicides belong to the group of the most widely used herbicides worldwide. In this review paper, encompassing mostly the relevant research and publications done in the last decade, the fate of triazine herbicides after their introduction in the environment will be discussed. They are transformed in a variety of transformation products after their application, and some of these produc...

The 1,3,5-triazine electron acceptor has become one of the most popular building blocks for design thermally activated delayed fluorescence (TADF) materials. Many TADF strategies are first applied in compounds that contain triazines, and there numerous examples organic light-emitting diodes (OLEDs) with triazine-containing emitters show high efficiencies long operating lifetimes. A comprehensiv...

Two new covalent triazines frameworks (CTFs) containing phenyl extended naphthalene units (with and without methoxy groups in the core) are prepared by thermal microwave activation. Both procedures yield similar chemical structures combining triazine acceptor with donor aromatic groups, but they generate some differences morphology, structural organization, CO2 adsorption capacity, optical prop...

The decrease of the number of ring nitrogen atoms of 2-benzylamino-4-methyl-6-trifluoromethyl-1,3,5-triazines on herbicidal activity and inhibition of photosynthetic electron transport (PET) was assayed using thylakoids from Spinacia oleracea or atrazine-resistant Chenopodium album. Three 2-benzylamino-4-methyl-6-trifluoromethyl-1,3,5-triazines, nine pyrimidines with a benzylamino-, methyl- and...

The use of microwave heating for preparation in organic synthesis has been accepted as an effective technique in synthesis due to the significant advantages over the conventional method. In the present work, microwave heating was applied to the preparation of atrazine (template molecule) magnetic molecularly imprinted polymer (mag-MIP) beads by suspension polymerization. The term of the polymer...

Novel glycosidic compounds, 4,6-dialkoxy-1,3,5-triazin-2-yl β-lactosides (DAT-β-Lac), have been prepared directly in water from lactose. The reaction was carried out on a laboratory scale without protecting the hydroxy groups of lactose. The resulting triazine derivatives were found to be recognized by endo-β1,4-glucanase III from Trichoderma reesei (EGIII). The EGIII-catalysed transglycosylati...

In the title compound, C(10)H(12)N(6), the two 5,6-dimethyl-1,2,4-triazine halves of the mol-ecule are related by a centre of symmetry. The two triazine rings are coplanar to within a maximum deviation of 0.013 (2) Å from the mean plane of the ring atoms. In the crystal, mol-ecules form layers parallel to the (100) crystallographic plane. Adjacent layers are held together via a C-H⋯π inter-acti...
