(E)-1,5-Di-phenyl-pent-2-en-4-yn-1-one.

ABSTRACT: The title compound, C17H12O, has an E conformation about the C=C bond. The C-C C-C torsion angle is 7.7?(2)°, and the mean planes of the phenyl-ethyl-enone [r.m.s. deviation = 0.059?(1)?Å] and phenyl-acetyl-ene [r.m.s. deviation = 0.023?(1)?Å] fragments form a dihedral angle of 14.16?(7)°. In the crystal, weak C-H?O inter-actions link the mol-ecules into zigzag chains propagated in [010].

4-(2-Chloro-phenyl-amino)-pent-3-en-2-one.

Project description:In the title compound, C(11)H(12)ClNO, intra-molecular N-H?O hydrogen bonding is present. The dihedral angle between the benzene ring and the pentenone unit is 46.52?(5)°. In the crystal, C-H?O inter-actions between hydrogen atoms of the aryl moiety and two separate oxygen atoms occur, leading to a three-dimensional network.

Project description:The title compound, C21H19N3O, exhibits an E configuration with respect to the C=C bond between the benzodiazepine and tri-methyl-amine groups. The seven-membered diazepine ring displays a boat conformation. In the crystal, mol-ecules are linked by a C-H?O hydrogen bond, forming a chain along [110].

(Z)-4-(2,5-Di-tert-butyl-anilino)pent-3-en-2-one.

Project description:In the crystal structure of the title ketoamine, C(19)H(29)NO, the bond lengths from the N atom through the alkene group to the ketone O atom show the presence of an extensively delocalized ?-system. The dihedral angle between the plane of the phenyl ring and that of the alkene component is 63.45?(7)° due to steric hindrance exerted by the tert-butyl groups. The mol-ecule has a Z-configured alkene function, which is facilitated by an intra-molecular N-H?O hydrogen bond between the amine and ketone groups. The mol-ecules are linked into extended chains, which run parallel to the [010] direction, by a very weak C-H?O inter-action between the methyl substituent of the alkene group and the ketone O atom of a neighbouring mol-ecule.

4-Phenyl-1-(prop-2-yn-1-yl)-1H-1,5-benzodiazepin-2(3H)-one.

Project description:4-Phenyl-1H-1,5-benzodiazepin-2(3H)-one reacts in the pres-ence of a concentrated aqueous solution of sodium hydroxide and a quaternary ammonium salt (as catalyst) in benzene (phase transfer catalysis) with propargyl bromide, affording the title benzodiazepine derivative, C(18)H(14)N(2)O. In the mol-ecule, the mean plane of the propargyl substituent is almost perpendicular with that of the amide group [dihedral angle = 87.81?(8)°]. In the crystal, the molecules are linked by C-H?O and C-H?N inter-actions.

Crystal structure of (E)-1-(2,4-di-nitro-phen-yl)-2-[(E)-5-phenyl-1-(p-tol-yl)pent-2-en-4-yn-1-yl-idene]hydrazine.

Project description:In the title compound, C24H18N4O4, the plane of the phenyl ring is inclined to those of the toluene ring and the di-nitro-substituted benzene ring by 66.96?(19) and 47.06?(18)°, respectively, while the planes of the two benzene rings are inclined to one another by 36.26?(19)°. There is an intra-molecular N-H?O hydrogen bond between the NH group and the O atom of a nitro group, forming an S(6) ring motif. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds and C-H?? inter-actions, forming a three-dimensional network. There are also weak ?-? inter-actions present involving the phenyl ring and the di-nitro-substituted benzene ring [inter-centroid distance = 3.741?(2)?Å].

Project description:The title compound, C(20)H(22)O(2), crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, all the non-H atoms lie in a common plane (r.m.s. deviations of 0.098 and 0.079?Å). There is a ?-? stacking inter-action in the crystal structure. The central aromatic rings of the two mol-ecules, which are stacked head-to-tail one above the other, are separated by centroid-to-centroid distances of 3.872?(13) and 3.999?(10)?Å.

Project description:The title compound, C(45)H(27)P, was obtained as a product of the reaction of triphenyl-methyl-enephospho-rane with one molar equivalent of 1,4-diphenyl-butadiyne in toluene. The compound was very stable under ambient conditions, but rapidly decomposed in solution when exposed to the air. The P atom is tetra-coordinated in an approximately tetrahedral geometry. The length of the C C triple bond [1.206?(2)?Å] is in the normal range.

1,5-Bis(penta-fluoro-phen-yl)-3-phenyl-pent-2-ene-1,5-dione.

Project description:In the title compound, C(23)H(8)F(10)O(2), the three arene rings are twisted one with respect to the other: the two perfluorinated arene rings are tilted to each other by an angle of 60.39?(7)°. They are inclined to the non-fluorinated phenyl unit by 38.85?(7) and 78.74?(7)°. The olefinic double bond adopts an E configuration. The carbonyl groups are not in a coplanar alignment with reference to the neighbouring arene rings. The crystal packing features a number of weak C-H?F inter-actions, which leads to the formation of a three-dimensional network.

Crystal structures of (<i>E</i>)-5-(4-methyl-phen-yl)-1-(pyridin-2-yl)pent-2-en-4-yn-1-one and [3,4-bis(phenyl-ethyn-yl)cyclo-butane-1,2-di-yl]bis-(pyridin-2-yl-methanone).

Project description:Recrystallization of (E)-5-phenyl-1-(pyridin-2-yl)pent-2-en-4-yn-1-one at room temperature from ethyl-ene glycol in daylight afforded [3,4-bis-(phenyl-ethyn-yl)cyclo-butane-1,2-di-yl)bis-(pyridin-2-yl-methanone], C32H22N2O2 (3), while (E)-5-(4-methyl-phen-yl)-1-(pyridin-2-yl)pent-2-en-4-yn-1-one, C17H13NO (2), remained photoinert. This is the first experimental evidence that pentenynones can be photoreactive when fixed in nearly coplanar parallel positions. During the photoreaction, the bond lengths and angles along the pentenyne chain changed significantly, while the disposition of the pyridyl ring towards the keto group was almost unchanged. The cyclo-butane ring adopts an rctt conformation.
