摘要

Alkali-metal (Li, Na) reductions of acetylenes in lowmolecular-weight amines and ammonia are well documented.'Dialkylacetylenes afford the corresponding trans-alkenesla while terminal acetylenes are primarily metalated. lb However, terminal acetylenes can be reduced quantitatively to the corresponding terminal alkeneslb by sodium in liquid ammonia containing ammonium sulfate. By contrast, lithium2 in ethylenediamine reduces 1-heptyne ...
