Easy access to o‐acyl acetanilides: A new Pd‐catalyzed ortho‐acylation of acetanilides with both aromatic and aliphatic aldehydes has been developed based on a CH activation process. In the presence of tert‐butyl hydroperoxide (TBHP) as the ideal oxidant, this reaction provides an efficient access to ortho‐acyl acetanilides in good yields (see scheme).
方便地访问 ö酰基乙酰苯胺: -催化的钯的新邻用芳族和脂族醛乙酰苯胺的酰化已经基于一个C已经开发 ħ激活过程。在存在叔丁基过氧化氢(TBHP)作为理想氧化剂的情况下,该反应可高效获得高收率的邻酰基乙酰苯胺(参见方案)。
