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
