Quantitative Structure-Activity Relationships of the Herbicidal N-Benzyl-2-bromo-3, 3-dimethyl- butanamides*
parameters and multiple regression analysis. The variation in the activity of N-(ca-substituted benzyl) derivatives was shown to be related parabolically with variation in the steric dimension of the substituents. The greater the hydrophobicity of substituents is, the greater the activity is. The variation in the steric dimension of the benzene ring substituents was responsible for the activity...
متن کاملDimethyl 4-(3-hydroxyphenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate
The 1,4-dihydro-pyridine ring in the title compound, C(17)H(19)NO(5), has a flattened-boat conformation, and the benzene ring is almost orthogonal to it [dihedral angle = 82.98 (12)°]. The hydr-oxy group is disordered over two positions in a 0.780 (4):0.220 (4) ratio. In the crystal, hydrogen-bonding inter-actions of the type N(a)-H⋯O(c) and O(h)-H⋯O(c) (a = amine, c = carbonyl and h = hydr-oxy...
متن کامل3-(4-Chlorophenylsulfonyl)-2,5-dimethyl-1-benzofuran
In the title compound, C(16)H(13)ClO(3)S, the 4-chloro-phenyl ring makes a dihedral angle of 79.96 (5)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked through weak inter-molecular C-H⋯O and C-H⋯π inter-actions.
متن کامل3-(4-Chlorophenylsulfinyl)-2,5-dimethyl-1-benzofuran
In the crystal structure of the title compound, C(16)H(13)ClO(2)S, the 4-chloro-phenyl ring is oriented approximately perpendicular to the benzofuran ring plane [dihedral angle = 82.45 (5)°]. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.
متن کامل3-(4-Fluorophenylsulfinyl)-2,5-dimethyl-1-benzofuran
In the title compound, C(16)H(13)FO(2)S, the O atom and the 4-fluoro-phenyl group of the 4-fluoro-phenyl-sulfinyl substituent are located on opposite sides of the plane through the benzofuran fragment; the 4-fluoro-phenyl ring is nearly perpendicular to this plane, making a dihedral angle of 87.41 (3). The crystal structure exhibits a weak inter-molecular C-H⋯O hydrogen bond.
