Organoalkali metal compounds are important reagents for introducing organic groups into organic and organometallic compounds in substitution or addition reactions. For example, active ingredients in widely used oral contraceptives contain alkynyl groups that are introduced by the addition of alkali metal acetylides to steroidal ketones. Organoalkali metal compounds show a pronounced tendency toward aggregation, and alkali metal acetylides are no exception. 3, record 1, English, - metallic%20acetylide

In the presence of moisture, acetylene can react with copper, silver and mercury to form metallic acetylides that are shock-sensitive, explosive compounds. 4, record 1, English, - metallic%20acetylide

Dans les dénominations de familles de composés, l'adjectif anglais «metallic» ou le terme anglais «metal» employé adjectivement se traduisent en français par «métallique» de préférence à «de métal». P. ex. : acétylures métalliques, azides métalliques, azotures métalliques, carbonoperoxoates métalliques, chlorures métalliques, cyanures métalliques, hydroxydes métalliques, hydrures métalliques, nitrates métalliques, sels métalliques, stéarates métalliques et sulfures métalliques (tournures plus naturelles que celles formées avec «de métal»). En revanche, lorsqu'il est nécessaire de préciser la nature du métal (métaux alcalins, métaux alcalino-terreux, métaux de transition, métaux des terres rares, métaux lourds, etc.), il est préférable, pour éviter toute ambiguïté, d'utiliser la locution «de métal». P. ex. : peroxydes de métaux de transition (et non «peroxydes métalliques de transition»), peroxydes de métaux alcalins (et non «peroxydes métalliques alcalins»). 5, record 1, French, - ac%C3%A9tylure%20m%C3%A9tallique
