Abstract
Exchange reactions (i)(X = Cl, Br, F, CN, NCS, NCO, or BH3CN) of Me3N,BH2I give high yields in tetrahydrofuran. Monoglyme and acetonitrile are less suitable solvents. The new compounds Me3N,BH2(NCS) and Me3N,BH2I + MX → Me3N,BH2X + MI (i) Me3N,BH2(NCO) have been isolated and characterised. A convenient two-stage preparation of Me3N,BH2(CN)(78% yield) from Me3N,BH3via in situ formation of Me3N,BH2I is described. The compounds Me3N,BH2X (X = Cl or Br) and Me3N,BHX2(X = Br or I) do not appear to undergo similar exchange reactions.Keywords
