  Design of Bicyclic and Cage Boron Compounds Based on Allylboration of Acetylenes with Allyldichloroboranes

  摘要：

  Allylboration of acetylenes with allyldichloroboranes has been proposed as a first step of allyl boron-acetylene condensation and a way to design condensation products from stage to stage. The chemistry has been applied to the synthesis of isomeric 3-borabicyclo[3.3.1]non-6-enes transformed into 3-methyl-1-boraadamantane and [5-D]-3-methyl-1-boraadamantane derivatives.

• Synthesis and Characterization of Allylic Dihaloboranes
  作者：Stéphanie Le Serre、Jean-Claude Guillemin

  DOI：10.1021/om9706471

  日期：1997.12.1

  Volatile allylic dihaloboranes have been prepared and characterized by H-1, B-11, C-13, and F-19 NMR spectroscopy and mass spectrometry. The stability (tau(1/2)) of such compounds in dilute CDCl3 solutions depends on the substituents and the halides and ranges from a few minutes (allylic dibromoboranes) to several days (allylic difluoroboranes). Allyldihaloborane etherates were obtained by addition of diethyl ether to the corresponding free allyldihaloborane.
