## Abstract The rate of the acid‐catalysed hydrosis of 7‐__syn__‐diazoacetyl‐2‐norbornene (**1a**) is enhanced relative to that of the saturated analogue **5a** by a factor of 835. In contrast to the behaviour of other primary diazoketones, the substitution step is no longer rate‐determining (mecha
