Tris(pyrazolyl)hydroboratozinc alkyl derivatives: direct comparison of the reactivity of Zn-C and Mg-C bonds

Abstract
The monoalkyl zinc derivatives [η3-HB(3-Butpz)3]ZnR (3-Butpz = 3-C3N2ButH2; R = Me, Et) have been prepared by metathesis of R2Zn with Tl[HB(3-Butpz)3], and their reactivity compared with that of the isostructural magnesium alkyl derivatives.
