o ‐Aminobenzenesulfonic acid → 4,5‐diphenylimidazole [DPI] forms an unstable 1:2‐chromium complex, accordingly the D REW ‐P FITZNER arrangement is indicated. o ‐Aminobenzenesulfonic acid ethylamide → DPI yields no chromium complex, whilst 1,3‐di‐(2‐aminobenzolsulfonamido)‐propane → DPI forms an unstable pentacyclic chromium complex.
