چکیده
Abstract A new solvent/ligand-controlled switchable C–H arylation of 1-methyl-4-nitro-1H-indazole catalyzed by Pd(OAc)2 was achieved. bidentate ligand in DMA promoted the activation at C7 position, while a phosphine H2O oriented C3 position. The and products were obtained moderate to good yields with high regioselectivity.

The fused five- and six-membered rings in the title mol-ecule, C10H9N3O2, are essentially coplanar, the largest deviation from the mean plane being 0.012 (1) Å for the C atom linked to the nitro group. The fused-ring system makes a dihedral angle of 11.34 (6)° with the nitro group, leading to a syn-periplanar conformation. The plane through the atoms forming the allyl group is nearly perpendicu...

The asymmetric unit of the title compound, C(9)H(8)N(2)O(2), contains two mol-ecules. In the crystal structure, both mol-ecules form inversion dimers via pairs of O-H⋯O hydrogen bonds, and a C-H⋯O inter-ation is also seen.

The mol-ecule of the title compound, C8H6ClN3O2, is built up from fused five- and six-membered rings connected to a chlorine atom and to nitro and methyl groups. The indazole system is essentially planar with the largest deviation from the mean plane being 0.007 (2) Å. No classical hydrogen bonds are observed in the structure. Two mol-ecules form a dimer organised by a symmetry centre via a clo...

In the title compound, C10H8ClN3O2, the indazole ring system makes a dihedral angle of 7.9 (3)° with the plane through the nitro group. The allyl group is rotated out of the plane of the indazole ring system [N-N-C-C torsion angle = 104.28 (19)°]. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming zigzag chains propagating along the b-axis direction.

In the title compound, C(10)H(6)BrN(3)O(2), the indazole fused-ring system is nearly planar (r.m.s. deviation = 0.008 Å); its nitro substituent is nearly coplanar with the fused ring [dihedral angle = 4.5 (2)°]. In the crystal, adjacent mol-ecules are linked by weak acetyl-ene-nitro C-H⋯O hydrogen bonds, generating a helical chain running along the b axis.
