    • Usually, the complex 1 is heated over 60 °C to provide a reasonable activity. The high activity of 4 at room temperature has been applied to the DKR of secondary alcohols with subtilisin, which is a thermally labile lipase, to produce (S)-acetates: Kim, M-.J.; Chung, Y.; Choi, Y.

    • 1H NMR at -78 to +25 °C in the hope of finding a clue to the cooperative participation of acetophenone and 1-phenyl-ethanol in the catalytic action of 14. However, only 14 was observed with its initial amount maintained.
