Conclusions
-
1.
It was shown by the cryoscopy method that in benzene solution, in the concentration range 0.03–0.1 mole/liter, the dibromo(dialkylamino)boranes exist predominantly as the monomers.
-
2.
The values of the11B NMR chemical shifts of the studied dibromo(dialkylamino)- and dibromo(diphenylamlno)boranes testify to their existence in the monomeric form also in the absence of a solvent, i.e., in either the liquid or molten state.
