실험 절차

The first step of Example 1 was repeated employing as the reactants, 5.6 ml trichloroacetyl chloride (50 mmol), 5 g (60 mmol) 4-methyl-1,3-pentadiene, 4.6 ml (50 mmol) phosphoryl chloride, 5 g (78 mmol) zinc and 500 ml ether. The yield was 6.8 g. or 71% theoretical, boiling at 65°-67° C. at 0.2 torr.
