Abstract

The reaction between the phosphine-borane-substituted alkene {Pr n2P(BH3)}(Me3Si)C=CH2 and elemental lithium in THF yields the complex [(pmdeta)Li{Prn2P(BH3)}(Me3Si)CCH2]2 (2b) after recrystallisation; an X-ray crystallographic study of 2b reveals that the lithium is bound to the BH3 hydrogens of the ligand, with no Li-C(carbanion) contact.
