Precise deuterium incorporation with controllable deuterated sites is extremely desirable. Here, a facile and efficient electrocatalytic deuterodehalogenation of halides using D2O as the deuteration reagent and copper nanowire arrays (Cu NWAs) electrochemically formed in situ as the cathode was demonstrated. A cross‐coupling of carbon and deuterium free radicals might be involved for this ipso‐selective
精确地将氘与可控制的氘位结合在一起是非常需要的。在此,使用D 2进行卤化物的便捷高效的电催化氘代脱卤化氢作为氘化试剂的O和作为阴极原位电化学形成的铜纳米线阵列(Cu NWAs)被证明。碳与氘自由基的交叉偶联可能导致这种ipso选择性氘化。该方法表现出优异的化学选择性,并且与易还原的官能团(C = C,C = C,C = O,C = N,C = N)具有高度的相容性。通过一锅式卤化-氘代脱卤化过程,可以实现高产和高氘比的CH-C转换。活性较低的溴化物底物的有效氘化,畅销药物中特定的氘掺入以及低能量输入的无氧化剂成对高价值化学品的阳极阳极合成突出了潜在的实用性。
