1.Boron tribromide adds to 1-octene, 1-hexene, and 3-hexene with formation of the corresponding bromobisbromoalkylboranes and trisbromoalkylboranes.2.Boron tribromide does not add to 2,4,4-trimethyl-1-pentene, but the latter dimerizes in presence of boron tribromide.3.When bromobis-2-bromooctylborane is treated with 1-butanethiol the successive replacement of bromine atoms of butylthio groups occurs. Reaction of tris-2-bromooctylborane with 1-butanethiol gives butyl bis[2-(butylthio)octyl]borinate.4.When bromobis-2-bromooctylborane and tris-2-bromooctylborane are treated with alcohols or hydrogen bromide, octene is eliminated and, under the conditions of the experiment, dimerizes. |
