摘要

A conceivable alternative route to 4 is through an intermediate organozinc compound of the type BrZnCF2COCl, but two pieces of evidence indicate otherwise. Perfluoroalkylzinc halides are of such low reactivity that heptafluoropropylzinc iodide has even been prepared in acetone.'In addition, if an organozinc intermediate were basic enough to attack acetone, the resulting anion would be expected to polymerize lactone 4 rather than ring close, ...
