Abstract:

The reactions of pentamethylcyclopentadienylin-diumI InC5Me5 with white phosphorus P4 at 175 deg C and of neopentylgalliumI GaCH2CMe3n with P4 at 350- 400 deg C and with NH3 at 460-480 deg C in sealed tubes provide routes to indium phosphide, gallium phosphide and hexagonal gallium nitride, respectively. The formation of these group 13-15 materials as black solids was confirmed by their X-ray photoelectron spectra, X-ray powder diffraction patterns and physical properties. The other products were C5Me52 in the case of the reaction of InC5Me5 with P4, neo- pentane and H2 in the case of the GaCH2CMe3n - NH3 reaction, and unidentified hydrocarbons and H2 in the case of GaCH2CMe3n - P4. These products were isolated and identified by 1H NMR spectroscopy or their physical properties, as appropriate. Carbon contamination in all materials was indicated by their XPS spectra and confirmed by combustion analysis.
