Can protons be swapped in a chemical reaction?

Can the protons of two elements be swapped in a chemical reaction? 




Roughly speaking, no. This would amount to nuclear fission/fusion, and is generally not considered "chemistry" in any colloquial sense of the term, but rather physics. 


In general, chemical reactions consider nuclei to be tightly bound by the [*strong force*](https://en.wikipedia.org/wiki/Strong_interaction), and immutable over the course of the reaction.


Disclaimer: there is an ill-defined border between physics and chemistry, and so one could argue that I am wrong about this. Indeed, *alchemists* had/have been trying to e.g. convert lead to gold for centuries, and this is related to the reaction that you propose.
