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 کامل2-Amino-5-chloropyridinium salicylate
In the crystal structure of the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(3) (-), the protonated N atom and the 2-amino group of the cation are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming R(2) (2)(8) ring motifs. These motifs are centrosymmetrically paired via N-H⋯O hydrogen bonds, forming a complementary donor-donor-acceptor-acceptor (DDAA) array. A t...
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 ...
متن کامل1-(2-Bromophenyl)ethane-1,2-diyl 1,1′-biphenyl-2,2′-dicarboxylate
In the title compound, C(22)H(15)BrO(4), the bromo-benzene ring is inclined at dihedral angles of 23.87 (11) and 52.37 (11)° with respect to the planes of the two benzene rings. The two benzene rings of the biphenyl unit form a dihedral angle of 49.08 (11)°. In the crystal, mol-ecules are linked into [100] chains by C-H⋯O hydrogen bonds.
متن کاملSYNTHESIS AND PHARMACOLOGICAL EVALUATION OF 6-CARBETHOXY-5-(3'-BROMOPHENYL)-3-ARYL-2-CYCLOHEXENONES AND 6-ARYL-4-(3'-BROMOPHENYL)-3-OXO-2,3A,4,5-TETRAHYDRO-2H-INDAZOLES
6-Carbethoxy-5-(3'-bromophenyl)-3-aryl-2-cyclohexenones 2a-j were obtained from the1-Aryl-3-(3'-bromophenyl)-2-propene-1-ones 1a-j by Micheal addition of ethyl acetoacetate, followed by internal Claisen condensation. Reaction of 2a-j with hydrazine hydrate afforded the corresponding 6-Aryl-4-(3'-bromophenyl)-3-oxo-2,3a,4,5-tetrahydro-2H-indazoles 3a-j. The structures of newly synthesized compou...
