Technology Process of SF₅N=SCl₂

There total 3 articles about SF₅N=SCl₂ which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 35.0%

((pentafluorosulfanyl)imino)difluorosulfane (13774-70-4) + antimonypentachloride (7647-18-9) → SF5N=SCl2 (25502-15-2) + ((pentafluorosulfanyl)imino)chlorofluorosulfane (80997-19-9) + antimony pentafluoride (7783-70-2)

Guidance literature:

sulfane was condesed on SbCl5 at -196°C, heated at 100°C to initiate the reaction; fractionation through a series of traps at -6, -45, -78, -112 and -196°C in vac., a -45°C trap contained the product;

Reference yield: 9.6%

thionyl chloride (7719-09-7) + thiazyl trifluoride (15930-75-3) + hydrogen fluoride (7664-39-3,12381-92-9,32057-09-3,74835-82-8) → SF5N=SCl2 (25502-15-2) + ((pentafluorosulfanyl)imino)chlorofluorosulfane (80997-19-9) + thionyl fluoride (7783-42-8)

Guidance literature:

HF and NSF3 were condesed in Kel-F reactor at -196°C, allowed toreact at room temp. overnight, SOCl2 added, reacted at room temp. for 2weeks and volatile products were condensed into a NaF scrubber; fractionation through a series of traps at -10, -78, and -196°C in vac., a -78°C trap contained the product, distillation;

Reference yield:

disulfur dichloride (10025-67-9) + F5SNCl2 (22650-46-0) → pentafluorosulfanyl chloride (13780-57-9) + SF5N=SCl2 (25502-15-2)

Guidance literature:

In further solvent(s); Cl2S2 is placed in a FEP-trap (dry-box), evacuated and cooled to -196°C, CFCl3 is condensed into trap, mixt. is warmed to room temp., into this mixt. Fe5SNCl2 is condensed (liquid N2), cooling to -100°C, mixt. is allowed to warm; mixt. is stirred under warming to -20°C for several hours, sepn.by fractional condensation in oil vac. in cold traps at -45, -50, -196°C, react. is followed by Raman-spectroscopy;
