Copper(I)-N-heterocyclic-carbene (NHC) complexes enabled the catalytic generation of nucleophilic hydrides from dihydrogen (H ) and their subsequent transfer to allylic chlorides. The highly chemoselective catalyst displayed no concomitant hydrogenation reactivity; in fact, the terminal double bond formed in the hydride transfer remained intact. Switching to deuterium gas (D ) allowed for regioselective monodeuteration with excellent isotope incorporation.
铜(I)-N-杂环卡宾(NHC)配合物能够催化由氢气(H₂)生成亲核氢化物,并随后将其转移至烯丙基氯上。这种具有高度化学选择性的催化剂没有伴随氢化反应活性;事实上,在氢化物转移过程中形成的末端双键保持完整。改用氘气(D₂)可实现区域选择性单氘代,且具有优异的同位素掺入率。
