An Uncomplexed 1,2,3-Triborolane Derivative

Abstract

(3,4,4a,7a,8,8a)-1,2,3-Tris(diisopropylamino)-1,2,3,3a,44a,5,7a,8,8a-decahydro-4,8-methanoindeno[5,6-d]-1,2,3-triborol (1) is formed from dicyclopentadiene and dichloro(diisopropylamino)borane upon treatment with sodium/potassium alloy in hexane. 1,2,3-Tris(diiso propylamino)triborane(5) (2) was also obtained. 1 is characterized by elemental analyses, spectroscopic data, and by an X-ray structure analysis, 2 by its MS and NMR data.
