Reduction of {(Me3Si)2CH}PCl(C6H 4-2-CH2OMe) withLiAlH4, followed by reaction with BH3·SMe2, gives the phosphane-borane {(Me 3Si)2CH}PH(BH3)(C6H 4-2-CH2OMe) (2) in good yield. Compound 2 undergoes rapid deprotonation on treatment with nBuLi, PhCH2Na or PhCH2K to give the corresponding alkali metal phosphido-borane complexes [[{(Me 3Si)2CH}P(BH3)(C6H 4-2-CH2OMe)]ML]2 [ML = Li(THF) (3), Na(tmeda) (4), K(pmdeta) (5)] after crystallization in the presence of the respective co-ligand L. The exact binding mode of the phosphido-borane ligand depends on the nature of the metal center in each case. However, all three alkali metal complexes crystallize as discrete dimers exhibiting M-P, M-O and M·BH3 contacts. Copyright
