213 mg (1.59 mmol) of 3-phenyl-2-propen-1-ol in 1.1 ml of ethanol were treated at 45° C. with stirring into 22 ml of buffer solution (see Example 1) with 24.3 mg (0.180 mmol) of 1-hydroxy-1H-benzotriazole. After approx. 10 minutes, 5 ml of an aqueous solution of 2 mg/ml laccase from Trametes versicolor (specific activity approx. 18 IU/mg, defined with ABTS as the substrate) were added. After 3 hours in contact with the air, 48% of 3-phenyl-2-propenal were formed (GC analysis), and a further 24.3 mg of HOBT and 5 ml of laccase solution were added. GC analysis after 6 hours revealed complete conversion into 3-phenyl-2-propenal.
