I have a question concerning the following page on Rh's page:
https://www.thevespiary.org/rhodium/Rhodium/chemistry/thiophenol.thiourea.html
The patent describes the reaction between a aryl halide and thiourea to yield a thiophenol after addition of aqueous NaOH. My question: what is the intermediate of the reaction between the aryl halide and thiourea? Is it the thiouronium salt or another compound?
