Fig. 1. Single-crystal X-ray structures of HFIP: (a) View perpendicular to the
helix axis; (b) view along the helix structure
(see above). Figure 3 shows the suggested optimal transition state structures for oxygen transfer from hydrogen peroxide to Z-2-butene in the
presence of two (Fig. 3a) and three (Fig. 3b) HFIP molecules. In sum-
