## Abstract Pseudo‐first‐order rate constants __k__~(obs)~ for the (concave) pyridine‐catalyzed addition of ethanol to diphenylketene have been determined photometrically. The catalytic activity of the concave pyridines 1 or 2 is determined by their basicity __and__ by their size. This effects a di
