چکیده انگلیسی
The reactions of R2P–P(SiMe3)2 (R = Ph, iPr and iPr2N) with BuLi in THF or DME solution lead to ion-contacted lithium derivatives R2P–P(SiMe3)Li · 3THF (R = iPr, iPr2N) with tetrahedrally surrounded Li atoms and to the solvent-separated ionic [Li · 3DME]+[Ph2P–PSiMe3]− with an octahedrally surrounded Li atom as confirmed by X-ray crystal structure analysis. The reaction of BuLi with Ph2P–P(SiMe3)2 is accompanied with a significant side-reaction leading to Ph2P–PPh2 and to LiP(SiMe3)2.
