Germanium tetraiodide

Germanium tetraiodide (3 g) and sufficient (CFsl Hg to provide molar ratios (of mercurial to germane) of 0.55, 0.98, 1.72, and 2.00 were placed in tubes (10-mm diam.) that were then degassed, sealed, and placed in an oven held at 120°. After 120 hours, the tubes were opened, and the contents separated. The yields of the (trifiuoro-methyDgermanium halides formed (16), based on Gel<, are presented in Table III. 

As these results indicate, the reaction of (CF3)2Hg with germanium tetraiodide provides a convenient source of the (trifluoromethyl)ger-manium iodides in good to excellent yields, and these yields can be varied, to increase the proportion of a particular (trifluoromethyl) germa-... 

Germanium and germanium tetraiodide did not react under these conditions3. 2-Trifluoromethylcyclohexyl trifluoromethyl tellurium decomposes in day light and extrudes tellurium on irradiation4. 

When germanium tetraiodide is treated with NHg the compound Ge(NH)2 is obtained [cf. NCNHg). Heating to 150 converts this to germanam, the germanium analogue of silicam and cyanimide ...
