Abstract
The results of the thermal decomposition and the reactions of endo-2,4-ethylenetetraborane are described. About 40% endo-2,4-ethylenetetraborane decomposes when left at 30 °c for one hour. The main products of the thermal decomposition are diborane and hydrogen. The reactions of endo-2,4-ethylenetetraborane with diethylether, tetrahydrofuran, ammonia and trimethylamine are described. The results are discussed and compared with the corresponding tetraborane reactions. It is concluded that reactions of endo-2,4-ethylenetetraborane with these Lewis bases result in B-C bond cleavage followed by intermolecular reactions to yield polymeric compounds and n-butane. The boron-hydrogen framework cleaves to give products analogous to those formed in the corresponding reactions of tetraborane.
