合成不稳定的磷杂炔3的起始化合物的选择已被证明是(二氯烷基)膦2。它们是用AlHCl2还原磷酸盐形成的，并在气相中用热的K2CO3(230-350℃)进行脱氢卤化。简单的磷杂炔3在室温下也能稳定地存在于四氢呋喃中--谁会想到这一点呢！R=H、Me、Et、NBU、Me3Si。
The choice of starting compoundfor the synthesis of the unstabilized phosphaalkynes3has proved to be the (dichloroalkyl)phosphanes2. They were formed by the reduction of the phosphonates1with AlHCl2and dehydrohalogenized over hot K2CO3(230–350°C) in the gas phase. The simple phosphaalkynes3are stable in THF at room temperature also—who would have expected that! R = H, Me, Et,nBu, Me3Si.
