method is described for the metal-free oxidation of o-vinyl diaryl ketones in the presence of molecular iodine or N-iodosuccinimide to give o-acetyl diaryl ketones. This transformation involves the initial formation of an iodohydrin, and the o-carbonyl group of the iodohydrin participates in a subsequent rearrangement to give the o-acetyl diaryl ketone. The presence and participation of ortho-carbonyl
描述了一种在分子碘或 N-碘代琥珀酰亚胺存在下无金属氧化邻乙烯基二芳基酮以得到邻乙酰基二芳基酮的新方法。这种转变涉及碘醇的初始形成,碘醇的邻羰基参与随后的重排以得到邻乙酰基二芳基酮。邻羰基的存在和参与是成功转化所必需的。设想的 1-甲基-4-芳基酞嗪由这些邻乙酰二芳基酮合成,并研究了它们对哺乳动物细胞系的抗增殖活性。
