Diethyl 2-(2-nitrobenzylidene)malonate
In the title compound, C(14)H(15)NO(6), the ethoxy-carbonyl groups adopt extended conformations. In the crystal, mol-ecules are linked into centrosymmetric dimers via pairs of C-H⋯O hydrogen bonds with a R(2) (2)(20) motif.
متن کاملDiethyl 2-(triphenylmethyl)malonate
In the title compound, C(26)H(26)O(4), steric crowding of the Ph(3)C- group with the -CH(CO(2)Et)(2) unit leads to a long C-C bond [1.585 (2) Å]. One of the two ethyl groups is disordered over two sites in a 60:40 ratio.
متن کاملDiethyl 2-{[2-(trifluoromethyl)anilino]methylidene}propanedioate
The title compound, C(15)H(16)F(3)NO(4), is an N-substituted derivative of ortho-trifluoro-methyl-aniline featuring a twofold Michael system. The least-squares planes defined by the atoms of the phenyl ring and the atoms of the Michael system enclose an angle of 15.52 (5)°. Apart from classical intra-molecular N-H⋯O and N-H⋯F hydrogen bonds, inter-molecular C-H⋯O contacts are observed, the latt...
متن کاملDiethyl 2-{[3-(2-methoxybenzyl)thiophen-2-yl]methylidene}malonate
In the title compound, C(20)H(22)O(5)S, the dihedral angle between the mean planes through the thio-phene and benzene rings is 75.2 (1)°. The meth-oxy group is essentially coplanar with the benzene ring, the largest deviation from the mean plane being 0.019 (2) Å for the O atom. The malonate group assumes an extended conformation.
متن کامل2-(9,9-Diethyl-9H-fluoren-2-yl)-1-benzofuran
In the title compound, C(25)H(22)O, the dihedral angle between the benzofuran and fluorene ring systems is 9.06 (6)°, and that between the two benzene rings of the fluorene system is 1.78 (12)°. Weak inter-molecular C-H⋯π inter-actions help to stabilize the crystal structure.
