Abstract
Reactions of bis(pinacolato)diboron (B 2 pin 2 ) with [(IDip)AlH 3 ] {IDip = (HCNDip) 2 C:, Dip = 2,6‐ i Pr 2 C 6 H 3 } afforded both the new diborane [(IDip)BH 2 B(pin)] and the known compound [(IDip)BH 2 BH 2 (IDip)] in a facile one‐pot procedure; the latter reaction is improved by the addition of free IDip. [(IDip)AlH 3 ] transfers both IDip and hydride ligands to the diborane moiety in a halide‐free approach. [(IDip)BH 2 B(pin)] was structurally and spectroscopically characterised and additional spectroscopic data for [(IDip)BH 2 BH 2 (IDip)] is reported.
