limitedly applicable in the cases of functionalized derivatives. One of the convenient methods to prepare 1,4-cyclohexadiene derivatives is cycloaddition of conjugated dienes to the acetylenes containing acceptor substituents (the Diels–Alder reaction). The Diels–Alder reaction of dimethyl chloroacetylenephosphonate and tetramethyl acetylenediphosphonate with some dienes leads to formation of the phosphorus-containing
1,4-环己二烯和类似的碳氢化合物可以通过芳烃与液态氨中的金属进行 Birch 还原来制备 [3]。然而,这种方法在功能化衍生物的情况下是有限适用的。制备 1,4-环己二烯衍生物的方便方法之一是将共轭二烯环加成到含有受体取代基的乙炔上(Diels-Alder 反应)。氯乙炔膦酸二甲酯和乙炔二膦酸四甲酯与一些二烯的 Diels-Alder 反应导致形成含磷的 1,4-环己二烯衍生物 [4-6]。
