| Abstract: | Reactions of (tBu)2P? P?P(Br)tBu2 with LiP(SiMe3)2, LiPMe2 and LiMe, LitBu and LinBu The reactions of (tBu)2P? P?P(Br)tBu2 1 with LiP(SiMe3)2 2 yield (Me3Si)2P? P(SiMe3)2 4 and PP(tBu)2]2P(SiMe3)2 5 , whereas 1 with LiPMe2 2 yields P2Me4 6 and P(tBu)2]2PMe2 7 . 1 with LiMe yields the ylid tBu2P? P?P(Me)tBu2 (main product) and tBu2P]2PMe 15 . In the reaction of 1 with tBuLi tBu2P]2PH 11 is the main product and also tBuP? P?P(R)tBu2 21 is formed. The reaction of 1 with nBuLi leads to tBu2P]2PnBu 17 (main product) and tBu2P? P?P(nBu)tBu2 22 (secondary product). |
