Through formation of a contact pair , bases are capable of transferring mobile protons from one molecular site to another. NMR experiments on a solution of diaryl‐triazene 1 in ethyl methyl ether in the presence of trimethylamine ( 2 ) [Eq. (a)] verify that the contact pair does not dissociate in the process.
