摘要

The double oxidation of halophenols with hypervalent iodine reagents in methanol provides a simple procedure to prepare halo-1, 4-benzoquinone monoketals. Seven examples of this procedure are reported as is the conversion of 3-iodo-4, 4-dimethoxycyclohexa-2, 5-dienone into the natural product,(−)-harveynone.
