Abstract: | The reaction of n-BuLi with phenyldiferrocenylphosphine oxide yields a mixture of two isomeric dianions. This mixture reacts with Me3SiCl, Br2, CO2, PhCHO and PhCHNPh to give bifunctional products. With CoCl2, Me2SiCl2, Ph2SiCl2, Bu2SnCl2 and PhCOOEt, the same mixture gives cyclic products. In almost every case each of these compounds is a mixture of two isomers corresponding to the original compound. The characteristic patterns of the PMR spectra are in full agreement with the structures proposed for the isomeric dianions. |
