How could I prepare a peach smelling compound?

There is a pictograph on the first page of this thread with esters and images representing what they smell like and 7 of them ARE LITERALLY A PICTURE OF A PEACH. Please, if you can't learn how to use a search engine, can you at least READ YOUR OWN THREAD?

Once you've selected a peachy ester that you can make, go look up Fisher esterification.

Alongside the Fischer method, you can also use sodium alkoxide + acyl chloride if you can get your hands on the latter but these would be difficult to obtain outside of personal synthesis - this would be more appropriate for larger esters as they cannot be distilled off before water and would subsequently be contaminated by the acid. NaOR + R’COCl -> NaCl + R’COOR. Separation of the sodium chloride generated is trivial, and the reaction doesn’t exist in equilibrium. Alkoxides are made by combining the alcohol with sodium metal or distilling with sodium hydroxide to remove water:

2 Na + 2 ROH -> 2 NaOR + H2
NaOH + ROH <-> NaOR + H2O




In chemistry, sometimes the solution is the problem.

It’s been a while, but I’m not dead! Updated 7/1/2020. Shout out to Aga, we got along well.

thank you,

I did have an ester in mind, but I didn't know what reaction mechanism was needed.

You lazy fuck. Google would have told you that in seconds, just search "ester + reaction".

It just wasn't occuring to me, I know... Either that or nothing showed up for the benzyl methanoate I tried looking up.

I was kinda asking moreso which peach compound is best to work with and if there's anything in particular I should watch out for.

I don't have a grasp on organic chemistry.
What's the first step?
