The first catalytic alkynylation of unactivated C(sp(3))-H bonds has been accomplished. The method allows for the straightforward introduction of an ethynyl group into aliphatic acid derivatives under palladium catalysis. This new reaction can be applied to the rapid elaboration of complex aliphatic acids, for example, via azide/alkyne cycloaddition.
未活化的 C(sp(3))-H 键的第一次催化炔化已经完成。该方法允许在钯催化下将乙炔基直接引入到脂肪酸衍生物中。这种新反应可用于复杂脂肪酸的快速制备,例如,通过叠氮化物/炔烃环加成反应。
