Versuchsvorschrift

The decarbonylation reaction was repeated in the manner as described in Example 70, except that the amount of tetraphenylphosphonium chloride was changed as set forth in Table 11, that the phenyl chloroglyoxylate was replaced with 1.396 mmol. of 4-methoxyphenyl chloroglyoxylate (4-MeO--PCG), and that the reaction temperature and reaction period were changed as set forth in Table 11. The results are also set forth in Table 11.
