文摘
Dihydrogen bonded complexes BH⋯HOR are the intermediates of cascade borohydride alcoholysis. The consecutive introduction of RO groups instead of hydride ligands decreases the dihydrogen bond strength. The BH bond polarization and hydride donor ability increase with substitution. The HH bond formation is a result of concerted proton and hydride transfer in transition state.
