Thiazyl trifluoride
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. 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.Preparation
NSF3 can be synthesised by the fluorination of thiazyl fluoride, NSF, with silver fluoride, AgF2:
or by the oxidative decomposition of FCNSF2 by silver fluoride:
It is also a product of the oxidation of ammonia by disulfur decafluoride|.Reactions
NSF3 reacts with carbonyl fluoride in the presence of hydrogen fluoride to form pentafluorosulfanyl isocyanate.
