Article abstract of DOI:10.1021/om100454t

The reaction between the phosphine-borane {(Me₃Si)CH ₂}₂P(BH₃)Ph (2) and 2 equiv of n-BuLi in THF yields the 1,3-dicarbanion complex (THF)₂Li{(Me₃SiCH) ₂P(BH₃)Ph}Li(THF)₃ (3), which crystallizes as an unusual contact ion pair. In solution 3 is subject to dynamic exchange which interconverts the two lithium environments.
