formal hydride transfer to the boron gives iron-borohydrido-hydride complexes. These
compounds catalyze the hydrogenation of alkenes and alkynes to the respective alkanes.
Notably, the boron is capable of acting as a shuttle for hydride transfer to substrates. The
results are interesting in the context of heterolytic substrate addition across metal–boron
bonds in metallaboratranes and related systems, as well as metal–ligand bifunctional …
