Abstract

The rapid photoinduced alcoholysis of the octahydrotriborate(1-) anion was observed from the UV irradiation of solutions of (Bu₄N)B₃H₈ and either ethanol or methanol in THF or chloroform. The octahydrotriborate(1-) anion, which is stable to alcoholysis in the ground state, reacts cleanly and rapidly with the alcohols to give HB(OC₂H₅)₂ and B(OC₂H₅)₃ products. Photolysis of (Bu₄N)B₃H₈ and C₂H₅OD gave both DB(OC₂H₅)₂ and HB(OC₂H₅)₂, as well as B(OC₂H₅)₃. A mechanism is proposed to accommodate these observations.
