Reactions of (Me2N)3P with functionalized di- and trichlorocyclopentenones
摘要:
2,3-Dichloro-4,4-ethylenedioxycyclopent-2-enone, its 5-chloroderivative, and 5-allyl-2,3,5-trichloro-4,4-dimethoxycyclopent-2-enone react with (Me2N)(3)P to give the corresponding products of substitution of the NMe2 group for the vinylic Cl atom at C(3).
