Ketone in charge: A formal ketone‐directed palladium‐catalyzed ortho‐hydroxylation of arenes has been developed as an effective approach to access o‐acylphenols from simple arylketones. A Pd‐catalyzed oxidative ortho‐carbonylation reaction using ketone directing groups to access a ketal–lactone motif is also demonstrated. The ubiquity and versatile nature of ketones make these methods attractive. BTI=PhI(TFA)2;
负责的酮:已开发出正式的酮导向的钯催化芳烃的邻羟基化反应,作为从简单的芳基酮中获得邻酰基苯酚的有效方法。还显示了使用酮引导基团访问缩酮-内酯基序的Pd催化的氧化邻位羰基化反应。酮的普遍性和通用性使这些方法具有吸引力。BTI = PhI(TFA)2;DCE = 1,2-二氯乙烷
