Highly Efficient Double-Activation Catalysts for the Synthesis of Ketone Cyano— A highly efficient catalytic system for the addition of Tms-CN towards
07- 028 hydrins.
aromatic and aliphatic ketones (V), (VII) is developed. The catalytic system consists of
a salen—Et3Al complex that activates the starting ketone and a nitrone that activates
the Tms-CN. Excellent yields are achieved with as low as 0.25 mol% of catalyst. —
