Summary
The crystal structure of a brominated organic compound reveals a significant dihedral angle between its benzene rings. Molecules form chains through weak hydrogen bonds in the solid state.
Area of Science:
- Crystallography
- Organic Chemistry
- Solid-State Chemistry
Background:
- Understanding the three-dimensional arrangement of atoms in organic molecules is crucial for predicting their properties.
- Intermolecular interactions, such as hydrogen bonds, play a significant role in the formation of crystal structures and material properties.
Purpose of the Study:
- To elucidate the crystal structure of the title compound, C(16)H(15)BrO(2).
- To investigate the dihedral angle between the benzene rings within the molecule.
- To identify and describe the intermolecular interactions present in the crystal lattice.
Main Methods:
- Single-crystal X-ray diffraction was employed to determine the molecular and crystal structure.
- Analysis of the crystal structure included measuring key bond lengths, bond angles, and dihedral angles.
- Identification of intermolecular interactions was performed by analyzing short non-bonded contacts.
Main Results:
- The crystal structure of C(16)H(15)BrO(2) was successfully determined.
- A dihedral angle of 68.5(2)° was measured between the two benzene rings.
- Molecules are organized into chains parallel to the b axis, mediated by weak C-H⋯O hydrogen bonds.
Conclusions:
- The study provides detailed structural information for the title brominated organic compound.
- The observed dihedral angle suggests a specific conformation of the molecule in the solid state.
- The identified C-H⋯O hydrogen bonding network dictates the supramolecular assembly and chain formation.

Criteria for Aromaticity and the Hückel 4n + 2 Rule
13.4K
Like benzene, cyclobutadiene and cyclooctatetraene are cyclic compounds with alternate single and double bonds. However, their chemical behavior differs from benzene, as they are unstable and not aromatic. So, what are the structural characteristics of unsaturated compounds categorized as aromatic?
For the first time, Eric Hückel, a German chemical physicist, derived a set of structural features for a compound to be classified as aromatic. This is now known as Hückel’s rule or the 4n +...

[4+2] Cycloaddition of Conjugated Dienes: Diels–Alder Reaction
12.6K
The Diels–Alder reaction is an example of a thermal pericyclic reaction between a conjugated diene and an alkene or alkyne, commonly referred to as a dienophile. The reaction involves a concerted movement of six π electrons, four from the diene and two from the dienophile, forming an unsaturated six-membered ring. As a result, these reactions are classified as [4+2] cycloadditions.

5-Number Summary
5.7K
In a dataset, the 5-number summary includes the minimum data value, the data value of the first quartile, the median data value or data value of the second quartile, the data value of the third quartile, and the maximum data value. These 5 data values can be visualized as a box and whisker plot.
In a box plot, the minimum and maximum data values represent the lower and upper whiskers in the graph, and the median is designated as the center of the box in the chart. The first quartile and third...

Dipeptidyl Peptidase 4 Inhibitors
687
Dipeptidyl peptidase 4 (DPP-4) is a serine protease widely distributed in the body. It's involved in the inactivation of GLP-1 and GIP hormones, which are crucial for insulin regulation. DPP-4 inhibitors, such as sitagliptin (Januvia), saxagliptin (Onglyza), linagliptin (Tradjenta), alogliptin (Nesina), and vildagliptin (Galvus), help increase the proportion of active GLP-1, enhancing insulin secretion. These inhibitors work by competitively binding to DPP-4. This binding causes a...

Phase II Reactions: Methylation Reactions
747
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...

meta-Directing Deactivators: –NO2, –CN, –CHO, –⁠CO2R, –COR, –CO2H
6.7K
All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...
