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 ...

In the title compound, C(11)H(14)ClNO, the herbicide propachlor, there are significant differences between the three N-C bond lengths [N-C(carbon-yl) = 1.354 (3) Å, N-C(phen-yl) = 1.444 (2) Å and N-C(isoprop-yl) = 1.496 (3) Å], indicating the presence of π delocalization involving the carbonyl group. The N atom lies 0.074 (2) Å from the plane defined by the the three bonded C atoms.

Interaction of acetonitrile with trifluoromethanesulfonic acid has been studied by multinuclear NMR and ESI-MS. It has been found that the interaction results in formation of a great variety of different cations and neutral compounds which is controlled by the ratio of CH(3)CN to TfOH. In the presence of an excess of the acid (molar ratio 1 : 8-14) diprotonated N-acetylacetamidine 1 is formed a...

the synthesis of 3-amino-1-nitroguanidine (3-anq) and 5-hydrazino tetrazole (5-ht) derivatives as new energetic materials are described. reaction of 3-anq with triethyl orthoformate leads to the formation of 3-nitramino triazole while no reaction was observed whit 5-ht. addition of nan3 to a mixture of 3-anq and triethyl orthoformate, afforded 1-nitroguanidyl tetrazole in excellent yield. on th...

In this study, an aromatic derivative was synthetized; the first stage involve the reaction of 3,17-Dihydroxy-13-methyl-7,8,9,11,12,13,-14,-15,16,17-decahydro-6H-cyclopenta[a]-phenanthrene-2,4-dicarbaldehyde (compound 1) with ethylenediamine to form 2,4-Bis-[(2-aminoethylimino)-methyl]-13-methyl-7,8,9,11,12,13,14,15,16,17-decahydro-6H-cyclopenta[a]phenanthrene-3,17-diol(3) using boric acid as c...
