between benzyl chlorides and metal acetylides, prepared from metallic lithium and sodium in liquid ammonia resulted in the formation of new compounds, i. e. 3,4-diphenyl-1-butyne and 3,4-diphenyl-1,2-butadiene. The benzylation of acetylene did not stop at benzylacetylene but another benzyl group was introduced to form 3,4-diphenyl-1-butyne. 3,4-Di-phenyl-1,2-butadiene was formed by the isomerisation of
在液氨中由金属锂和钠制备的苄基氯与金属炔化物之间的反应导致形成新化合物,即3,4-二苯基-1-丁炔和3,4-二苯基-1,2-丁二烯。乙炔的苄基化并没有在苄基乙炔处停止,而是引入了另一个苄基以形成 3,4-二苯基-1-丁炔。3,4-二苯基-1,2-丁二烯通过丁炔的异构化形成。这种异构化不仅通过热乙醇钾的作用发生,而且在室温下在液氨中也发生。3,4-二苯基-1,2-丁二烯很容易通过加热聚合。
