Reaction Conditions

Reaction Steps

A 250 ml round-bottomed flask fitted with a condenser, nitrogen purge, and addition funnel was charged with a solution of 89.7 g (0.45 mol) dicyclohexylphosphine and heated to 60° C. with stirring. To the flask was added 50.8 g (0.53 mol) 2-cyclohexen-1-one over a period of 0.5 hour. When addition was complete, the temperature of the contents of the flask was slowly raised to 90° C. and maintained at that temperature for 6 hours, then cooled. Unreacted starting materials were removed by evaporation under reduced pressure at 150° C.
