  Organoboranes. 56. Systematic study of the reactions of 1-alkenylboronic esters with representative organolithium and Grignard reagents to provide an efficient, selective synthesis of organyl-1-alkenylborinic esters

  摘要：

  A selective reaction of the ''ate'' complexes formed with 1-alkenylboronic esters and organolithium or Grignard reagents, by treatment with either Bronsted or Lewis acids at -78-degrees-C to give the corresponding organylalkenylborinic esters, is explored in this study. This systematic, detailed study reveals that the nature of the alkoxy group on boron, the nature and the amount of the alkyllithium or Grignard reagent used, the solvent, the reaction temperature, and the nature and amount of the acid used all play significant roles in influencing both the yield and the selectivity achieved for the formation of the desired organylalkenylborinates. Optimized procedures for the syntheses of representative organylalkenylborinic esters in high yield are summarized.

• Migration of 1-alkenyl groups from zirconium to boron compounds

  The reaction of dicyclopentadienylzirconium alkenyl chloride with a boron chloride or bromide results in the exchange of the halogen and alkenyl group, forming the alkenylborane. We report here a systematic investigation of the transmetalation of the 1-hexenyl group from zirconium to a variety of boron compounds. This group undergoes facile migration to a variety of boron compounds, yielding structurally different types of alkenylboranes in good to high yields. These results suggest that one can combine the unique reactivity and selectivity of hydrozirconation for the preparation of alkenylboranes.
