# Electrophilic substitution on Borazole

As Borazole ($$\ce{B3N3H6}$$) is aromatic, it can show electrophilic aromatic substitution. Now, my question is when borazole undergoes electrophilic aromatic substitution reaction, on which atom does the electrophile attack? Is it boron or nitrogen? Also, how to compare it's rate with the same type of reaction when carried on benzene? Should I consider stability of arenium ion (Wheland intermediate) formed when comparing the rates?

• Borazole isn't really that aromatic if compared to benzene. I'd expect electrophiles to add to nitrogen. Aug 5 '20 at 10:12
