2018年3月21日 · I would like to know how exactly is $\ce{AcOH}$ participating in these two reactions. Is it supporting the generation of electrophile? If yes, then how? I couldn't find any relevant information on the net. The second reaction is from Clayden's book and it doesn't highlight the role of $\ce{AcOH}$ there.

2017年5月5日 · With NBS/$\\ce{CCl4}$ allylic bromination occurs. But with NBS/$\\ce{AcOH}$ bromination occurs on the alkene double bond. Why does this difference occur and how? I.e what will be the mechanisms of both?

2022年8月15日 · I am unsure of how to go about designing a mechanism for the following molecule's reaction with AcONa and AcOH with heat. I thought perhaps it may work as a cyclisation reaction, forming an ether; or perhaps a decarboxylation. I've tried many of these mechanisms and none of them seem to give an answer that seems correct.

2019年10月23日 · Your reaction goes way back to 1930s when Ingold and coworkers have done pioneering work on nitration of aromatic compounds using nitric acid in organic solvents in place of sulfuric acid (vide infra).

2018年4月1日 · Other reductive methods: $\ce {Zn/AcOH}$, triphenylphosphine ($\ce {PPh3}$), or thiourea ($\ce {NH2C(=S)NH2}$). Note: Recently, there is a publications claiming an efficient and convenient method for reductive workup of the ozonolysis reaction using sodium hydrosulfite.

Going back to the original question I can't see what the role of AcOH is. I would have thought that $\ce{AcOH/H_2SO_4}$ is a very nice way to make an acetate (esterification) but if you plan to dehydrate then I am not sure what AcOH helps with. Not much help sorry, hopefully someone else could answer this $\endgroup$ –

2019年3月17日 · $$[\ce{AcO-}] = C_\mathrm{a} - [\ce{AcOH}] \approx 0.001$$ $$\alpha = \frac{[\ce{AcO-}]}{C_\mathrm{a}} \approx 1.8 \%$$ So you see, in a more dilute mixture the $\mathrm{pH}$ is higher, and the dissociation reaction of acetic acid is 'more complete', whereas at higher concentration the pH is lower, and there is proportionally less acetate anion.

2017年3月20日 · Aldehydes, including aldoses, are oxidized to their respective carboxylic acids in the presence of $\ce{Br2}$ in $\ce{H2O}$.

2021年5月24日 · In chloroform a polymeric mono-ozonide is obtained. In MeOH the reaction takes a different course resulting in the formation of a cyclic methoxy-hydroxy-peroxide and a cyclic dimethoxy-peroxide. Reductive work up (Zn/AcOH or Me2S) of …
