## Abstract The __N__‐diazo coupling of __p__‐chloroaniline with __p__‐chlorobenzenediazonium tetrafluoroborate in acetonitrile at 30° shows non‐linear base catalysis by water. The results are interpreted in terms of the __S__~__E__~2 mechanism with rate‐limiting proton loss at low base concentrati
