General description
Carbon tetrafluoride (CF4), also known as tetrafluoromethane, belongs to the class of fluoromethanes. It can be prepared by the reaction of silicon carbide with fluorine. It is used as a refrigerant.
Application
Carbon tetrafluoride can be used in fluorine chemistry for the preparation of organofluorine compounds. It is also used as a solvent in low-temperature reactions . During the manufacture of electronics devices, CF4 plasma is widely used to etch a variety of materials.
Packaging
Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

A laser flash photolysis-laser-induced fluorescence (LIF) technique has been employed to study the relaxation kinetics of vibrationally excited O2(X 3sigma(g)-. The time-resolved LIF excited B 3sigma(u)(-)-X 3sigma(g)- system has been recorded and analyzed by the integrated-profiles method. The rate coefficient

Evans-type chiral lithium imide enolates undergo diastereoselective α-trifluoromethylation with a hypervalent iodine-CF(3) reagent with up to 91% combined isolated yield and 97:3 dr. The resulting isolated diastereopure products can be further transformed into valuable products without racemization.
