Germyl fluoride

Freshly prepared lithium wire, and selenium and tellurium powders were used as supplied. Germyl fluoride may be prepared from germyl iodide11 and lead(II) fluoride.12 Chlorotrimethylsilane is distilled through traps at -45° (chlorobenzene-liquid N2 slush), -78° (methanol-dry ice slush), and -196° (liquid N2) the fraction retained in the trap at -78° is the desired purified chlorotrimethylsilane. Peroxide-free diethyl ether was distilled in a vacuum system from fresh Li[AlH4] and stored in vacuo. Caution. The use of Li[AlHA] for drying ethers can lead to explosions 3 Commercial dry NH3 (10-15 mL portion) was further dried by condensation onto Na pellets (about 1 g) in an ampul (about 50 mL) held at -78° on the vacuum line. After 30 minutes the dried NH3 was pumped from the ampul and degassed in a trap held at -196° before use. 

Characteristic of germyl fluorides, exchange processes lead to broadened featureless spectra in concentrated solutions.
