Diazomethane is a toxic yellow gas that is both sensitive and explosive. However, it is a useful reagent in the laboratory to make key intermediates by reacting with carboxylic acids in a quick and clean reaction. Draw the expected organic product of diazomethane with the following carboxylic acid.

Answer:

Carboxylic acids react with diazomethane to produce methyl esters.

Explanation:

Diazomethane has a high reactivity and is used to produce methyl esters with carboxylic acid in a immediately reaction, carried out at room temperature in the absence of catalysts.

As we can see in the image below

  • In the First Step, occurs an acid-base reaction to obtain the "carboxylate" ion.
  • Second Step: The Carboxylate attacks the protonated diazomethane by a SN2 reaction to finally get the Methyl Ester.

The subproduct is Nitrogen; knowing this, we must be careful with the production of this gas, and do the process in a vented place
