反応手順
The reaction described in Example 3 was substantially repeated except that the Cu,K-PFIEP[SO3H] catalyst was replaced by the Cu,K-PFIEP[SO3H]/PFIEP[CO2H] (0.58 g) catalyst described above. The reaction mixture was allowed to stir for 0.5 hour after the addition of the solution of ethyl diazoacetate, CH2Cl2 and styrene. Analysis by gas chromatography showed that the combined yield of cis- and trans-ethyl-2-phenylcyclopropanecarboxylates was 95%.
