The boron-boron bonds in the diborane(4) molecules (Me2N)2B-B(NMe2)2 (1), (Me2N)ClB-BCl(NMe2) (5) and Cl2B-BCl2 (8) as in B4Cl4 are cleaved by the chloramines Me2NCl (2), MeNCl2 and EtNCl2 (9).As oxydation products BCl3 or the corresponding aminoborane and diborylamines can be isolated.The interaction of 8 and 2 leads to the formation of Me2NH*BCl3 as additional product. - Elementary chlorine does not only cleave the B-B but also the B-N bond in 1, giving Me2NCl as one of the reaction products. - The properties of the N-ethylbis(dichloroboryl)amine (11) are discussed.
