Crystal structure of 1-[(Z)-2-phenyl­hydrazin-1-yl­idene]naphthalen-2(1H)-one

In the title compound, C16H12N2O, the dihedral angle between the planes of the benzene ring and naphthalenone ring system is 1.89 (8)°; an intra-molecular N-H⋯O hydrogen bond occurs between the imino group and the carbonyl group. In the crystal, mol-ecules are linked by weak C-H⋯π inter-actions into supra-molecular chains propagating along the [01-1] direction.

Crystal structure of (Z)-3-benz­yloxy-6-[(2-hy­droxy­anilino)methyl­idene]cyclo­hexa-2,4-dien-1-one

In the title compound, C20H17NO3, the methyl-idene-cyclo-hexa-2,4-dienone moiety is approximately planar [maximum deviation = 0.0615 (10) Å] and is oriented at diherdral angles of 69.60 (7) and 1.69 (9)° to the phenyl and hy-droxy-benzene rings, respectively. The amino group links with the carbonyl O atom via an intra-molecular N-H⋯O hydrogen bond, forming an S(6) ring motif. In the crystal, th...

wide interest because the 1H-pyridin-2-ones obtained in this process are versatile synthetic building blocks in the synthesis of alkaloids.1–5 The title compound, (–)-(1′R)-1-(2′-hydroxy-1′-phenyl-ethyl)1H-pyridin-2-one II, was prepared by stirring a solution of pyridinium salt, I (4.0 mmol), in water (25 ml) and cooled to 5 ̊C (Scheme 1). A solution of K3Fe(CN)6 (11 eq.) in water (30 ml) was ad...

Crystal structure of (Z)-2-(1-benzyl-2-oxoindolin-3-yl­idene)-N-phenyl­hydra­zine-1-carbo­thio­amide

The title compound, C22H18N4OS, crystallized with four independent mol-ecules (A, B, C and D) in the asymmetric unit. All four mol-ecules have a Z conformation about the C=N bond with the benzyl ring being inclined to the indoline ring mean planes by 73.4 (2), 77.9 (2), 73.2 (2) and 77.2 (2)° in mol-ecules A, B, C and D, respectively. In mol-ecules A and B, the phenyl ring is inclined to the me...

In the title indolinone derivative, C10H10INO, all the non-H atoms, except the terminal methyl C atom, are almost coplanar. The mol-ecules are arranged into columns extending along the a-axis direction and inter-act with the mol-ecules in adjacent columns via C-H⋯O hydrogen bonds [H⋯O distance = 2.57 (3) Å] and I⋯I short contacts of 3.8986 (3) Å. A one-dimensional zigzag iodine chain along the ...
