Germanium mercury halides

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. 

AMMONIA GAS (7664-41-7) Anhydrous, compressed gas or cryogenic liquid. Difficult to ignite, but can detonate in confined spaces in fire. Reacts violently with strong oxidizers, acids (nitric, hydrochloric, sulfuric, picric, hydrobromic, hydrochlorous, etc.). Shock-, temperature-, and pressure-sensitive compounds are formed with antimony, chlorine, germanium compounds, halogens, heavy metals, hydrocarbons, mercury oxide, silver compounds (azides, chlorides, nitrates, oxides). Fire and/or explosions may be caused by contact with acetaldehyde, acrolein, aldehydes, alkylene oxides, amides, antimony, boron, boron halides. 

Although methyl iodide does not react with ordinary forms of metallic thallium, the very finely divided metal reacts readily with methyl iodide in ether solution at room temperature or even at 0° C. At that time we remarked that this type of reaction was probably not confined to thallium, and other metals such as lead and probably tin, germanium, and mercury undergo similar reactions. Shortly thereafter we found that tetramethyllead could be prepared in excellent yields by the reaction of methyllithium or methyl-magnesium chloride and methyl iodide with lead halides according to the following ...
