synthesis of five-membered heteroarylethynes. The electron-impact induced fragmentation of the phosphoranes also produced ions corresponding in mass to the ethynes, but metastable ion data indicate that the extrusion of the ethyne follows the initial loss of H· from the molecular ion.
Trippett对芳酰基亚甲基膦酸酯的热解的修饰为五元杂芳基乙炔的合成提供了一般程序。电子撞击引起的膦烷裂解也产生质量与乙炔相对应的离子,但亚稳态离子数据表明乙炔的挤出遵循分子离子中H·的初始损失。
