In the title compound, C(13)H(14)N(2)O(3), the morpholine ring displays a chair conformation, with the (2,3-dioxoindolin-1-yl)methyl group in an equatorial position. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

A reaction of equimolar equivalents 1-(4-methoxyphenyl)-5-methyl-1H-1,2,3-triazole-4-carbohydrazide (1) and indoline-2,3-dione (2) in boiling ethanol for 4 h under acidic conditions gave 1-(4-methoxyphenyl)-5-methyl-N’-(2-oxoindolin-3-ylidene)-1H-1,2,3-triazole-4-carbohydrazide (3) 88% yield. The structure 3 was ascertained by NMR spectroscopy single-crystal X-ray diffraction.

In the title compound, C22H20ClN3O4, the central pyrrolidine ring adopts an envelope conformation on the N atom. The indolinone systems are individually roughly planar, with maximum deviations from their mean planes of 0.130 Å for the spiro C atom of the indolinone unit and 0.172 Å for the carbonyl C atom of the 5-chloro-1-methyl-indolinone unit. They make dihedral angles of 77.7 (8) and 86.1 (...

In the racemic title compound, C(14)H(16)N(2), the aromatic ring component of the amino-indoline system occupies the endo cavity of the norbornane component. The aromatic ring lies at an angle of 74.12 (5)° to the plane defined by the four C atoms that comprises the rigid part of the boat-shaped six-membered ring of the norbornane unit. Pairs of mol-ecules assemble in the crystal structure, for...

A redox amination strategy was developed for the synthesis of N-aryl-1-aminoindoles by N-N bond formation. Reaction of nitrosobenzenes with readily available indolines using Brønsted acid catalysis allows N-N bond formation under mild conditions. This method exploits the inherent reducing power of indoline to synthesize biologically relevant molecular architectures via redox amination. A one-po...

The addition of 2,6-dimethylphenyl isocyanide (CN[DMeP], two equivalents) to previously reported (PNP)Sc(III) pyridyl complexes resulted in the formation of novel indoline complexes of scandium. By varying the nature of the pyridyl moiety one can intercept an intermediate prior to methyl migration. In addition to structural studies of two indolene complexes, we also propose a mechanism for the ...

In the title compound, C(26)H(18)N(2)O(3), the maximum deviations from planarity for the tetra-hydro-1H-naphtho-[2,3-c]pyrrole and indoline rings systems are 0.091 (1) and 0.012 (2) Å, respectively. These ring systems make a dihedral angle of 89.95 (6)° with each other and they make dihedral angles of 73.42 (8) and 71.28 (9)°, respectively, with the benzene ring. In the crystal, inversion dimer...

The photophysical properties of two indoline-based octupolar merocyanine dyes and of the corresponding quinoline-based dyes were examined. This seemingly subtle structural change in the chromophore of these molecules has an appreciable effect on the yields with which these respective compounds sensitize the production of singlet molecular oxygen, O2(a(1)Δg). The indoline-based dyes are reasonab...
