The reaction of 3-chloropropenyl alkyl ketones or 2,3-dichloropropyl alkyl ketones with 2-substituted ethylamine derivatives leads to the formation of the hitherto unknown 1-(2-R-ethyl)-2-alkylpyrroles.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 8, pp. 1047–1049, August, 1990. 相似文献

A series of new 1-(2-arylvinyl)-2-azolyl-1-pyridylethanols-1 has been obtained with various positions of the nitrogen atom
in the pyridine fragment and with substituents in the benzene ring, by the reaction of (2-arylvinyloxiran-2-yl)pyridines with
triazole and imidazole, for agrochemical screening. The compounds mentioned displayed high fungicidal activity.

The title compound, C17H20O5, (I), is structurally related to naturally occurring 1-aryl-2-aryloxy-1-propanols. Such compounds are of interest as lignin models, and neolignans of this type have been detected in a large number of plants. In the crystal structure of (I), the molecules adopt a conformation in which the aryl groups are far apart from each other. The O(aryloxy)—C—C—C(aryl) torsion angle is 177.76 (14)°. The conformation is compared with those of other compounds (neolignans and lignin model compounds) of the 1-aryl-2-aryloxy-1-propanol type (including some acetate derivatives). The comparison shows that in all the examined compounds the above-mentioned torsion angle is close to 180°, and the distance between the centers of the aromatic rings approaches the maximum achievable in most of the compounds. The hydrogen-bonding pattern of (I) is discussed in terms of graph-set theory. 相似文献

The molecular geometry and vibrational frequencies of 1-(thiophen-2-yl-methyl)-2-(thiophen-2-yl)-1H-benzimidazole (C(16)H(12)N(2)S(2)) in the ground state has been calculated using the Hartree-Fock (HF) and density functional method (B3LYP) with 6-31G(d) basis set. The optimized geometric bond lengths and bond angles obtained by using HF and DFT (B3LYP) show the best agreement with the experimental data. Comparison of the observed fundamental vibrational frequencies of 1-(thiophen-2-yl-methyl)-2-(thiophen-2-yl)-1H-benzimidazole (C(16)H(12)N(2)S(2)) and calculated results by density functional B3LYP and Hartree-Fock methods indicate that B3LYP is superior to the scaled Hartree-Fock approach for molecular vibrational problems. 相似文献

The course of palladium-catalyzed oxidation of a terminal alkene by t-BuOOH or by O2/H2O is greatly modified when the allylic carbon bears a p-toluenesulfonyl substituent, and allylic oxidation results. Mechanistic explanations of this observation are proposed. 相似文献
