Extracting the product after a diazonium coupling reaction using diethyl ether.
Diazonium coupling is a reaction used to introduce a functional group via electrophilic substitution to an aromatic ring system, such as naphthalene in this case. In this reaction, methylferrocene was coupled to 6-amino-2-naphthoyl-methyl-ester. A diazonium salt needs to be prepared for the reaction ’in situ’, since the intermediate compound is too unstable to store. Once the salt is being prepared, it must not be allowed to reach a temperature above 5°C, or else the -N+≡N group rapidly decomposes into N2 gas and may cause an explosion due to the rapid increase of pressure within the flask.Â
