In the Arens–van Dorp synthesis the compound ethoxyacetylene [7] is converted to a Grignard reagent and reacted with a ketone, the reaction product is a propargyl alcohol. [ 8 ] [ 9 ] The Isler modification is a modification of Arens–Van Dorp Synthesis where ethoxyacetylene is replaced by β -chlorovinyl ethyl ether and lithium amide .
The reaction of quadricyclane with DEAD is a 2σ + 2σ + 2π cycloaddition that on water takes place within 10 minutes at room temperature with 82% yield. The same reaction in toluene takes 24 hours at 80 °C with 70% yield. An emulsion reaction in fluorinated cyclohexane takes 36 hours and the neat reaction takes even longer (48 hours).
Ethylamine is used as a precursor chemical along with benzonitrile (as opposed to o-chlorobenzonitrile and methylamine in ketamine synthesis) in the clandestine synthesis of cyclidine dissociative anesthetic agents (the analogue of ketamine which is missing the 2-chloro group on the phenyl ring, and its N-ethyl analog) which are closely related ...
2-Ethylanthraquinone is prepared from the reaction of phthalic anhydride and ethylbenzene: C 6 H 4 (CO) 2 O + C 6 H 5 Et → C 6 H 4 (CO) 2 C 6 H 3 Et + H 2 O. Both phthalic anhydride and ethylbenzene are readily available, being otherwise used in the large-scale production of plastics.
In organic synthesis, the complex diethylaniline·borane (DEANB) is used as a reducing agent. [4] Diethylaniline and dimethylaniline are both used as acid-absorbing bases. The advantage to the diethyl derivative is that [C 6 H 5 NEt 2 H]Cl is non-hygroscopic, in contrast to [C 6 H 5 NMe 2 H]Cl. [5]
It has been reported that formate can be formed by the electrochemical reduction of CO 2 (in the form of bicarbonate) at a lead cathode at pH 8.6: [24] HCO − 3 + H 2 O + 2e − → HCO − 2 + 2OH −. or CO 2 + H 2 O + 2e − → HCO − 2 + OH −. If the feed is CO 2 and oxygen is evolved at the anode, the total reaction is: CO 2 + OH − ...
Among other alkyl groups (R) ethyl-and tert-butyl-are used, e.g., 2-ethylanthraquinone. [2] [3] The hydrogen peroxide is then extracted with water and in a second step separated by fractional distillation from the water. The hydrogen peroxide accumulates as sump product. The anthraquinone acts as a catalyst, the overall reaction equation is ...
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O. Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis. It is a colorless liquid that smells strongly of acetic acid, which is formed by its reaction with ...
