The thermal decomposition of a number of organo-bielemental vanadium compounds with the general formula Cp2V(ER3) (ER3 = GeEt3, SnEt3, CH2SiMe3, SeGeEt3) has been investigated in solids and in solutions.The main decomposition products of Cp2V(SnEt3) are vanadocene and hexaethyldistannane.Et3GeH, Et3GeCp, Cp2V and CpV(C5H4GeEt3) are formed from Cp2V(GeEt3) decomposition.Isolated CpV(C5H4GeEt3) is characterized by IR and mass spectra.The decomposition of Cp2V(CH2SiMe3) is accompanied by Me4Si, Cp2V and CpV(C5H4CH2SiMe3) formation, the latter is identified from the mass spectrum.Triethylgermane, vanadocene, and a diselenide of vanadium are isolated on decomposition of Cp2V(SeGeEt3).Based upon the experimental data, mechanisms for the decomposition are proposed.
