Phenylacetylene is a prototypical terminal acetylene, undergoing many reactions expected of that functional group. It undergoes semi hydrogenation over Lindlar catalyst to give styrene . In the presence of base and copper(II) salts, it undergoes oxidative coupling to give diphenylbutadiyne . [ 6 ]
The physical reactions to LSD vary greatly and some may be a result of its psychological effects. Commonly observed symptoms include increased body temperature, blood sugar, and heart rate, as well as goose bumps, jaw clenching, dry mouth, and hyperreflexia. In cases of adverse reactions, users may experience numbness, weakness, nausea, and ...
Symptoms are typically vague and non-specific, such as fatigue or headaches. [12] These symptoms, although they can be disabling, are called non-specific because they are not associated with any single specific medical condition. Symptoms affect a variety of different organ systems.
The risk of first-degree relatives developing the same hypersensitivity reaction is higher than in the general population. [ 1 ] As this syndrome can present secondary to multiple anticonvulsants, the general term "anticonvulsant hypersensitivity syndrome" (AHS) is favored over the original descriptive term "dilantin hypersensitivity syndrome."
Serum sickness in humans is a reaction to proteins in antiserum derived from a non-human animal source, occurring 5–10 days after exposure. Symptoms often include a rash, joint pain, fever, and lymphadenopathy. It is a type of hypersensitivity, specifically immune complex hypersensitivity .
Yet another method involves the coupling of iodobenzene and the copper salt of phenylacetylene in the Castro-Stephens coupling. The related Sonogashira coupling involves the coupling of iodobenzene and phenylacetylene. Diphenylacetylene is a planar molecule. The central C≡C distance is 119.8 picometers. [1]
4-Hydroxyphenylacetone is the para-hydroxy analog of phenylacetone, an inactive metabolite of amphetamine in humans. [ 1 ] [ 2 ] When it occurs as a metabolite of amphetamine, it is produced directly from the inactive metabolite phenylacetone .
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility,numbness and tingling in the hands and feet. [1]
