SYNTHESIS AND MASS-SPECTRA OF TRIARYL-GALLIUM AND TRIARYL-INDIUM COMPOUNDS

The synthesis of a number of symmetrically 2-, 3-, and 4-substituted triaryl-gallium and triarylindium compounds are reported using transmetallation of the corresponding mercurial with Ga or In metal. The electron impact mass spectra of these compounds are very similar and very simple and show the basic structural features of the molecules. With careful control of the conditions it is possible to obtain spectra in which metal-containing ions are the dominant species with little contamination from hydrolysis and pyrolysis products. The spectra provide evidence for dimers of these compounds as significant gaseous species. © 1979.
