Figure 7.

Cage‐catalysed hydrolysis of dichlorvos [16.6 mm dichlorvos in borate‐buffered D₂O at pD 7.7 and 298 K, in the absence of cage H (blue traces) or the presence of H (0.64 mm; red traces)]. Top: evolution of ³¹P NMR spectra showing consumption of dichlorvos (−3 ppm) and appearance of dimethylphosphate (+3 ppm); a known amount of dimethyl methylphosphonate (δ=39 ppm) was present as a calibrant to allow quantitative integration of the ³¹P signals. Bottom: comparison of rates of product appearance in the absence and presence of H.
