Thiazyl trifluoride is a chemical compound of nitrogen, sulfur, and fluorine, having the formula NSF3. It exists as a stable, colourless gas, and is an important precursor to other sulfur-nitrogen-fluorine compounds. [2] It has tetrahedral molecular geometry around the sulfur atom, and is regarded to be a prime example of a compound that has a sulfur-nitrogen triple bond. [3]
NSF3 can be synthesised by the fluorination of thiazyl fluoride, NSF, with silver(II) fluoride, AgF2:
or by the oxidative decomposition of FC(O)NSF2 by silver(II) fluoride: [4]
It is also a product of the oxidation of ammonia by S2F10. [5]
NSF3 is much more stable than thiazyl fluoride, does not reacts with ammonia and hydrogen chloride, and only reacts with sodium at 400 °C. [6] It reacts with carbonyl fluoride (COF2) in the presence of hydrogen fluoride to form pentafluorosulfanyl isocyanate (SF5NCO). [7]
