- Multinuclear Nmr Study of the Reactivity of BCl3 with (Dimethylamino)dichloroarsine and (Dimethylamino)dimethylarsine
-
The reactions of BCl3 with Cl2AsNMe2 and Me2AsNMe2 have been carried out and followed by temperature-dependent (11)B, (13)C, and (1)H nmr.At -100 deg C, Cl2AsNMe2 forms Cl2AsNMe2BCl3.Decomposition of this adduct begins within a short time to yield Me2NBCl2 and AsCl3.At -100 deg C, Me2AsNMe2 gives equimolar amounts of the Me2AsNMe2*BCl3 and Me2AsNMe2*BCl3 adducts.The As-B and N-B adducts undergo rearrangement to intermediates that decompose ultimately to a mixture of Me2NBCl2 and Me2AsCl.The reaction of Me2NBCl2 with Me2AsNMe2, at -90 deg C, gives Me2AsNMe2*Me2NBCl2 which subsequently decomposes to (Me2N)2BCl and Me2AsCl.The nmr spectral data for these reactions and the intermediate reaction products are discussed.

- Oxidation of Diborane(4) Molecules by Chloramines
-
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.
