Abstract:

The thermal dealkylation of 2-chloro-4,6-bis(isobornylamino)-s-triazine (I), 2-chloro-4,6-bis(bornylamino)-s-triazine (II), 2-chloro-4,6-bis(exo-norbornylamino)-s-triazine (III) and 2-chloro-4,6-bis(endo-norbornylamino)-s-triazine (IV) was performed at 250 °C. The high degree of dealkylation in the case of isobornyl derivative I was ascribed to a reaction via a seven-membered cyclic transition state, as well as to steric interaction of the dimethylmethylene group and the triazine ring. The presence of tricyclenes in the dealkylation products of this derivative also indicates that the reaction

Abstract The QB binding site of photosystem II in green plants displays stereoselectivity for the (S′) stereoisomer of the α-methylbenzyl derivative of atrazine but not for derivatives with smaller substituents such as sec-butyl.

The intermolecular energy was calculated by van der Waals and electrostatic interactions after energy minimization of the combined structures to reduce inter and in

Abstract:

The spectroscopic data for a range of cyclopenta-[d][1,2,3]-triazine derivative dyes have been evaluated using various standard computational approaches. Absorption data of these dyes were obtained using the ZINDO/S semi-empirical model for vertical excitation energies of structures optimised with the AM1, PM3, and PM6 methods. These studies were conducted under vacuum and solution states using the polarisation continuum model (PCM) for implicit solvation in the linear response model. The accuracy, along with the modest computational costs of using the ZINDO/S prediction, combined with the PM3

Abstract:

Condensation of thiocarbamide with triethyl phosphonoacetate leads to S -phosphorylated 2-ethoxy-4-oxo3,4,5-trihydro-1,5,2-diazaphosphinine-2-oxide, an isostere of thiobarbiturate. Under similar conditions, triethyl phosphonoacetate reacts with semicarbazide with the intermediate formation of 2-(diethoxyphosphorylacetyl) hydrazine-1-carboxamide, which forms a triazine upon cleavage of the P-C bond and 1,2,3-phosphadiazole upon cleavage of the C-N bond. Under analogous conditions, the condensation of triethyl phosphonoacetate with thiosemicarbazide proceeds with cleavage of the Р-С bond and het

Abstract:

The crystal structure and topology analyses of a new bromo-Mn(II) complex with 2,4-bis(3,5dimethyl-1H-pyrazol-1-yl)-6-methoxy-1,3,5-triazine (MBPT) were reported. Its structure was confirmed using single-crystal X-ray diffraction to create the formula [Mn(MBPT)Br(H2O)2]ClO4. Its crystal system was monoclinic and its space group was p21. The Mn(II) was coordinated with MBPT as a NNN-pincer ligand, with one bromide ion in the equatorial plane. The two axial terminals were occupied by two trans water molecules. H…H, N…H, Br…H, C…H and O…H were the predominant intermolecular contacts, while Br…H,

A novel series of s-triazines incorporating 4-hydroxybenzaldehyde and 4-hydroxy-3-methoxybenzaldehyde was prepared and fully characterized. The reaction was carried out via stepwise nucleophilic aromatic substitution of chlorine atoms in cyanuric chloride. The first chlorine was substituted by different amines (morpholine, piperidine, or diethylamine) to afford 2,4-dichloro-6-substituted-1,3,5-triazine. The second and third chlorines were substituted by benzaldehyde derivatives in the presence of Na2CO3 as a HCl scavenger to afford the target products: s-triazine oxyaldehyde derivatives (dipod

The tri-s-triazine unit is substituted with two dipyridyl amine moieties and a carbonylic O atom. As indicated by the bond lengths in this acid unit of the heptazine derivative [C=O = 1.213 (2) Å, while the adjacent C—N(H) bond = 1.405 (2) Å] it is best described by the keto form.
