Limitations of Friedel–Crafts Reactions
0 Views •
2025
Several restrictions limit the use of Friedel–Crafts reactions. First, the halogen in the alkyl halide must be attached to an sp3-hybridized carbon for the Friedel–Crafts reactions to occur. Vinyl or aryl halides do not react since the carbocations formed are unstable under the reaction conditions. Second, Friedel–Crafts alkylation is susceptible to carbocation rearrangement, and the major products obtained have a rearranged carbon skeleton. In contrast, the acylium ion is stabilized by...

Electrophilic Aromatic Substitution: Friedel–Crafts Alkylation of Benzene
0 Views •
2023
Friedel–Crafts reactions were developed in 1877 by the French chemist Charles Friedel and the American chemist James Crafts. Friedel–Crafts alkylation refers to the replacement of an aromatic proton with an alkyl group via electrophilic aromatic substitution. A Lewis acid catalyst such as aluminum chloride reacts with an alkyl halide to form a carbocation. The resulting carbocation then reacts with the aromatic ring and undergoes a series of electron rearrangements before giving the final...

Electrophilic Aromatic Substitution: Friedel–Crafts Acylation of Benzene

2025
The Friedel–Crafts acylation reactions involve the addition of an acyl group to an aromatic ring. These reactions proceed via electrophilic aromatic substitution by employing an acyl chloride and a Lewis acid catalyst such as aluminum chloride to form aryl ketone. The mechanism involves the formation of a complex between the Lewis acid and the acyl chloride. An acylium ion is formed by the cleavage of the carbon-chlorine bond of the complex. The acylium ion has a positive charge on the carbon...

Here, we present a protocol to adapt the Taylor dispersion experiment to the microscale using microchannels fabricated in-house with a desktop craft cutter. The experimental platform can be used to compute the diffusion coefficient of single-species passive tracers and to visualize multispecies ion interaction and separation.

2024
We have developed a simplified and cost-effective approach for electrode fabrication and conducted recordings of signals across multiple regions in freely moving mice. Utilizing optogenetics, alongside multi-region electrophysiology and calcium signal recording, enabled the revelation of neuronal activities across regions in the seizure kindling model.
FAQs
The design is converted into tool paths, which specify how the blade should travel through the sheet. The cutter then coordinates directional movement with selected speed and cutting depth so the blade follows the intended geometry rather than treating the sheet as an undifferentiated surface. This digital-to-motion link lets a researcher change a pattern and produce a corresponding physical prototype quickly.
Direction, speed, and cutting depth are the main controllable conditions identified for the cutting operation. Direction determines how the blade traces the pattern, while speed and depth govern how the tool engages the sheet as it moves. Adjusting these variables is important because the intended result depends on following the digital geometry accurately across the chosen thin material.
Its main distinction is accessibility and turnaround rather than reliance on specialized machining infrastructure. The tool supports low-cost fabrication of patterned thin sheets, allowing researchers to move from a digital design to a testable item rapidly. That makes it useful when a project requires repeated geometry changes or early-stage physical evaluation before more elaborate fabrication.
Begin with a digital pattern, convert that pattern into tool paths, and set the cutting operation so the blade controls direction, speed, and depth while tracing the sheet. The resulting cut can then serve as the intended component or fabrication aid. This sequence links design revision directly to physical production and supports rapid benchtop iteration.
In bioengineering, cuts can be used to make stencils and masks, as well as flexible components and assembly aids. These outputs support benchtop experiments and device development, where researchers may need patterned or structured materials. The tool therefore serves both preparation and assembly needs, extending beyond simple shape production to support how experimental devices are built and tested.
It is especially useful when researchers need to test geometries, compare design iterations, or prepare structured materials without specialized machining equipment. Fast turnaround and low cost make it practical for early and repeated prototyping. In a benchtop bioengineering workflow, a revised digital pattern can therefore become a new stencil, mask, flexible element, or assembly aid for the next experiment.
