  Syntheses and solid-state structures of mono- and dialkyl(methylsulfonato)boranes

  摘要：

  R3B reacts with MeSO3H at elevated temperature in toluene to give liquid R2B(OSO2Me) [R = Et (la), 61%; R = Bu (Ib), 58%; R = Pr-i (Ic), 23%] and, in the case of Et3B and Bu3B, solid RB(OSO2Me)(2) [R = Et (2a), 13%; R = Bu (2b), 11%]. As (Pr3B)-B-i is less reactive, pivalic acid must be added as catalyst, and no formation of the disulfonatoborane is observed. Complexes la-e and 2a-b were characterised spectroscopically (IR,H-1-, C-13-, B-11-NMR), and crystal structure determinations were carried out on la, which is monomeric even in the solid state, and 2a and 2b, which are dimeric in the solid state and have two differently bonded sulfonate groups (terminal and bridging).
