在温和的碱(NaOAc)和过量的二硼试剂存在下,钯(II)-NHC络合物催化B-B键的新的催化活性使烯烃能够化学选择性地1,2-二硼化合,这表明二硼的异解裂解而不是B-B键的氧化加成。
Novel catalytic activation of the B-B bond by palladium(II)-NHC complexes in presence of a mild base (NaOAc) and an excess of diboron reagent enables chemoselective 1,2-diboration of alkenes, suggesting the heterolytic cleavage of diboron rather than oxidative addition of a B-B bond to the metal.
