2-(4-Bromophenyl)-2-methylpropanamide
In the crystal of the title compound, C(10)H(12)BrNO, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. Further N-H⋯O hydrogen bonds link the dimers into sheets propagating in (100).
متن کاملEthyl 5-(4-Bromophenyl)-4-methyl-1H-pyrrole- 2-carboxylate
This note describes a sequence converting an oxime-substituted pyrrolidine into a trisubstituted pyrrole structure. The synthetic route is based on a double chlorination of the pyrrolidine substrate followed by the base induced formation of both an imine and a nitrile oxide functionality. The latter reacts with an immobilized thiourea to yield an isothiocyanate which upon elimination generates ...

hydroquinazoline-2,5-dione was obtained from Biginelli-type cyclocondensation1 of 5,5-dimethylcyclohexane-1,3-dione with urea and 4-bromobenzaldehyde: yield 1.16 g (62.19%), m.p. 174 – 175 ̊C. A summary of the key crystallographic information is given in Table 1. The atomic coordinates and equivalent isotropic displacement parameters with estimated standard deviations for atoms except H are list...
متن کامل4-Ethoxy-N-(4-ethoxyphenyl)-N-(4-nitrophenyl)aniline
In the title mol-ecule, C22H22N2O4, the eth-oxy-phenyl rings are oriented at dihedral angles of 69.31 (13) and 75.90 (13)° to the nitro-phenyl ring and are twisted to each other, making a dihedral angle of 78.55 (13)°. In the crystal, weak C-H⋯O hydrogen bonds and C-H⋯π inter-action link the mol-ecules into a three-dimensional supra-molecular architecture.
متن کاملN 4,N 4′-Bis(4-methoxybenzylidene)-3,3′-dimethylbenzidine
The mol-ecule of the title compund, C(30)H(28)N(2)O(2), a Schiff base synthesised via a condensation reaction between 4-meth-oxy-benzaldehyde and 3,3'-dimethyl-benzidine, a crystallographic twofold rotation axis passes through the mid-point of the C-C bond of the biphenyl unit. Thus, the asymmetric unit comprises one half-mol-ecule. In the biphenyl unit, the aromatic rings are twisted by 13.49 ...
