Dipyrrylmethanes react with arenediazonium ions in acidsolution to form azopyrroles and formaldehyde. At low pH cleavage of the methylene bridge is brought about by attack of hydrogen ions, but at higher pH arenediazonium ions assume this role. In the reaction of benzylpyrrole, benzyl alcohol was detected as a product, suggesting formation of a benzyl carbonium ion. The relevance of these studies to the
