Stronger acid, higher speed : The p K a values of a range of binol‐derived Brønsted acids of three different types were measured and found to correlate directly with the catalytic properties of the acids: higher rate constants k I were observed for more acidic Brønsted acid catalysts (see plot; binol=1,1′‐bi‐2‐naphthol).
