Technical Note:
1. Widely used in complex multi-step organic syntheses. This mild hydration catalyst converts hindered and acid/base sensitive nitriles to amides. The amide is released from the metal coordination sphere preventing further hydrolysis to acid. Typically . turnover frequency (TOF) ranges from 16 to 380 h-1 depending on steric factors. For optimal results avoid the presence of coordinating anions especially cyanide and halide.
