Carbon tetrafiuoride

With the exception of carbon tetrafiuoride and silicon tetrachloride, all other halides, EX4, of Group IV metals react with BSD (27, 50, 63). Reactions with SiF4, GeCl4, and SnCl4 are discussed separately here because they run quite differently. 

Tungsten tetrafiuoride oxide is a white hygroscopic solid (mp 104.7 at 25 torr, bp 185.9°) which can be sublimed readily. It is soluble in HF and in propylene carbonate. The F NMR spectrum in propylene carbonate solution consists of a singlet at 65.2 ppm downfield from external CFCla, with two satellites with 7wf = 69 Hz."...
