摘要

1, 2-Benzenedisulfonimide (1) has previously been found to be an excellent and, importantly, safe Brønsted acid catalyst. In this work we present the results of a search for derivatives of 1 that are more acidic and effective. Instead of blindly synthesizing a series of analogues, we have carried out a screening process in which the pKa of 1 and a set of its derivatives were calculated. The calculated pKa values were confirmed experimentally by ...
