Diversity Lewis-acid controlled

Scheme S.7 Example for Lewis-acid controlled diversity-oriented synthesis [71].

By comparison with Lewis bases in superacids, there is a greater diversity of Lewis acids and of relative strengths of the acids in the three fluoro-acids under consideration. Each of the three acids will be presented separately in the remainder of this section. HF will be considered first because higher acidities occur in HF than in HSO3F and CF3SO3H and easier control of acidity can be achieved.
