Stronger acid, higher speed: The pKa values of a range of binol‐derived Brønstedacids of three different types were measured and found to correlate directly with the catalytic properties of the acids: higher rate constants kI were observed for more acidicBrønstedacidcatalysts (see plot; binol=1,1′‐bi‐2‐naphthol).
较强的酸,较高的速度: 测量了三种不同类型的由多元醇衍生的布朗斯台德酸的p K a值,发现与酸的催化性能直接相关:对于更酸性的布朗斯台德,观察到较高的速率常数k I酸催化剂(请参阅图表;二元醇= 1,1'-bi-2-萘酚)。
