An efficient method for the formation of C(sp)–N or C(sp)–P bonds is described. The facile transformation proceeds under mild conditions (0 or –20 °C) in a one‐pot manner, and does not require transition‐metal catalysts. The base‐induced protocol exhibits good functional group tolerance (up to 44 examples) and high efficiency (up to 94 % yield) towards rare heteroatom‐substituted acetylenes (N or P). Furthermore, the proposed mechanism was supported by the isolation of a key intermediate.
