实验过程

This compound is prepared in a manner analogous to that of Step C of Example 4, using 6.7 grams (0.04 mole) of 4-chlorophenylglyoxal (prepared by the method of Kornblum et al., JACS, (1957), 79, 6562), 29.5 grams (0.24 mole) of anhydrous chromium(II) dichloride, and 31.5 grams (0.08 mole) of iodoform in 600 mL of tetrahydrofuran, yielding 1-oxo-1-(4-chlorophenyl)-3-iodo-2-propene.
