Catalyst-controlled chemoselective arylation of 2-aminobenzimidazoles.
The chemoselective and complementary Pd-and Cu-catalyzed N-arylation of 2aminobenzimidazoles is described. Selective N-arylation of the amino-group was achieved with a Pd-catalyzed method, while selective N-arylation of azole nitrogen was achieved with a Cucatalyzed procedure. The utility of these complementary sets of conditions is demonstrated in several two-step, selective syntheses of di-ar...
متن کامل2-Nitro-N-phenylbenzenesulfonamide
In the title compound, C(12)H(10)N(2)O(4)S, the conformation of the N-H bond in the -SO(2)-NH- fragment is syn to the ortho-nitro group in the sulfonyl-benzene ring. The mol-ecule is twisted at the S-N bond, the C-N-S-C torsion angle being -72.83 (15)°. The dihedral angle between the benzene rings is 59.55 (7)°. The amide H atom and the nitro group O atom form an intra-molecular hydrogen bond, ...
متن کامل2-Nitro-1,3-dinitrooxypropane
The title compound, C3H5N3O8, was synthesized by reacting 2-nitro-propane-1,3-diol with acetyl nitrate. The mol-ecule is bisected by a crystallograpic mirror plane. In the crystal, the mol-ecules pack in a ribbon-like fashion along the c axis, with the central nitro groups pointing in the same direction. C-H⋯O contacts apparently provide some additional packing stabilization.
متن کامل4-Nitro-2-phenoxyaniline
In the title compound, C(12)H(10)N(2)O(3), the oxygen atom bridging the two aromatic rings is in a synperiplanar (+sp) conformation. The dihedral angle between the aromatic rings is 71.40 (12)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds.
