Description
It is shown, that exchange reaction between B10H12(SMe2)2 and triphenylphospohine is benzene leads to formation of B10H12(PPh3)2xPh solvate during B10H12(PPh3)2 synthesis. B10H12(PPh3)2x0.7CHCl3 is prepared by recrystallization of the latest solvate from chloroform, B10H12(PPh3)2 - from acetone. The composition is fixed after vacuum drying (1.3 Pa; 60 deg). In all cases, prepared crystals are amorphous ones. Pyrolysis of B10H12(PPh3)2 at 250 deg is accompained by the loss of 4 hydrogen and 0.05 triphenylphosphine moles. Besides hydrogen, benzene and methane are determined in gaseous phase. Formation of boron carbide and phosphide in solid phase at 750 deg isn't observed
