丁二炔
丁二炔（butadiyne）也称为联乙炔（Diacetylene），其分子式C4H2，是高度不饱和的碳氢化合物，含有二个三键及三个单键，是分子量最小的聚炔烃，「联乙炔」的名称表示其中有二个碳-碳的双键，而且可能是由乙炔制备，不过不表示这是乙炔的二聚体。

Diacetylene 丁二炔
Diacetylene (also known as butadiyne), with the formula C4H2, is a highly unsaturated hydrocarbon that contains three single bonds and two triple bonds. It is the first in the series of polyynes. The trivial name "diacetylene" refers to the two C-C triple bonds and the possible formation from acetylene (see below). It does not mean that diacetylene is the formal dimer of acetylene, what is rather true for butenyne or cyclobutadiene.
