文摘

Reversible, heterolytic addition of H₂ across an iron鈥揵oron bond in a ferraboratrane with 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鈥揵oron bonds in metallaboratranes and related systems, as well as metal鈥搇igand bifunctional catalysis.
