This study details the first use
of well-defined low-valent p-block
metal hydrides as catalysts in organic synthesis. That is, the bulky,
two-coordinate germanium(II) and tin(II) hydride complexes, L†(H)M: (M = Ge or Sn, L† = −N(Ar†)(SiPri3), Ar† = C6H2{C(H)Ph2}2Pri-2,6,4), are shown to act as efficient catalysts
for the hydroboration (with HBpin, pin = pinacolato) of a variety
of unactivated, and sometimes very bulky, carbonyl compounds. Catalyst
loadings as low as 0.05 mol % are required to achieve quantitative
conversions, with turnover frequencies in excess of 13 300
h–1 in some cases. This activity rivals that of
currently available catalysts used for such reactions.
