Darstellung und Charakterisierung von Organodilithiumphosphiden. Die Kristallstruktur von [Li(THF)(TMEDA)P(H)Mes]

Synthesis and Characterization of Organodilithium Phosphides. The Crystal Structure of Li(THF)(TMEDA)P(H)Mes] t-BuPH₂ and MesPH₂ can be reacted with two equivalents n-BuLi at R. T. in Et₂O/n-hexane to yield the corresponding organodilithium phosphides t-BuPLi₂ ( 1 ) and MesPLi₂ ( 2 ). 1 and 2 can be isolated solvent-free as bright orange-yellow solids. 1 and 2 were characterized by NMR, IR, and RE spectra. When MesPH₂ is treated with one equivalent of n-BuLi, MesP(H)Li is crystallizing as Li(THF)(TMEDA)P(H)Mes] ( 3 ) from THF/TMEDA/n-pentane in the space group P2₁/n with a = 893.41(6), b = 1 734.7(1), c = 1 391.1(1) pm and β = 90.613(6)°.
