| Abstract: | Reaction of Cp#MCl4, (1
or 2) [(1): M = Mo, Cp# =
Cp* (Cp* =  5-C5Me5) and (2): M = W, Cp#
= Cp (Cp = 5-C5H5)] with excess of [LiBH4.thf] followed by thermolysis with
excess of [HS(CH2)nSH] (n = 2 or 3), leads to the
formation of [(Cp*Mo)2B4H4S2] (3) or [(CpW)2B4H4S2] (4) respectively. Corresponding to (3)
and (4), the
compounds [(M)2B5H9]
(M = CpW, (5) or Cp*Mo, (6)) are
isolated as major product
in both the cases. These new compounds have been characterized in
solution by mass, 1H, 11B, 13C NMR spectroscopy.
The structural types have been unequivocally established by X-ray
crystallographic analysis of compounds (4). |
