Spiro[1,3-dioxolane-2,3′-indolin]-2′-one
The title compound, C(10)H(9)NO(3), was synthesized by the condensation reaction of isatin (systematic name 1H-indole-2,3-dione) with glycol in presence of p-toluene-sulfonic acid. The indol-2-one ring system is essentially planar [N-C-C-C torsion angle = 3.1 (2)°], and the 1,3-dioxolane ring is slightly distorted. The crystal structure exhibits inter-molecular N-H⋯O hydrogen bonds.

The title compound, C(10)H(8)ClNO(3), is a significant anti-convulsant agent. The indolinone system is essentially planar, the dihedral angle between the rings being 2.24 (8)°. The dioxolane ring adopts an envelope conformation; the dihedral angle between the plane through its four coplanar atoms and the indolinone system is 89.8 (1)°. The crystal structure is stabilized by a three-dimensional ...
متن کامل3-(Phenylimino)indolin-2-one
The imino C=N double bond in the title compound, C(14)H(10)N(2)O, exists in an E conformation, with the phenyl ring being twisted by 80.7 (1)° in one independent mol-ecule and by 81.4 (1)° in the other with respect to the plane of the indoline fused-ring system. The two independent mol-ecules are linked by N-H⋯O hydrogen bonds, forming a zigzag chain running along the a axis.
متن کامل3-(Diphenylmethylidene)indolin-2-one
The title mol-ecule, C(21)H(15)NO, has an indoline-2-one and two benzene substituent groups which are arranged in a propeller-like fashion around the central C atom. The dihedral angle between the two benzene rings is 73.32 (16)° and those between the benzene rings and the indoline-2-one group are 76.54 (14) and 67.69 (14)°. In the crystal, there is an inter-molecular N-H⋯O hydrogen-bonding int...
متن کامل3-[(E)-Benzylidene]indolin-2-one
In the title indolin-2-one derivative, C(15)H(11)NO, the phenyl ring and the oxoindoline fused-ring system (r.m.s. deviation = 0.011 Å) are aligned at 48.52 (6)°. In the crystal, inversion-related mol-ecules form an N-H⋯O hydrogen-bonded dimer via an eight-membered {⋯HNCO}(2) synthon. The dimeric aggregates are linked into a three-dimensional architecture via C-H⋯O and π-π inter-actions between...
