Various arylsulfur pentafluorides, ArSF(5), have long been desired in both academic and industrial areas, and ArSF(5) compounds have attracted considerable interest in many areas such as medicines, agrochemicals, and other new materials, since the highly stable SF(5) group is considered a "super-trifluoromethyl group" due to its significantly higher electronegativity and lipophilicity. This article
The synthesis and mechanism of formation of cis- and trans-Ph2SF4 is described. Starting compounds are Ph2S or Ph2SF2 and the oxidizing agent is XeF2 in the presence of Et4NCl. Also described is the synthesis of related chalcogen(IV and VI) fluorides such as t-butylSF3, difluorodibenzothiophene, PhSeF3, Ph2SeF2, PhSF5, p-MeC6H4SF5, PhSeF5, and PhTeF5. The reactions of Ph2S(O)F2 with alcohols and with
描述了顺-和反-Ph 2 SF 4的合成及其形成机理。在Et 4 NCl存在下,起始化合物为Ph 2 S或Ph 2 SF 2,氧化剂为XeF 2。还描述了相关的硫族元素的合成(IV和VI)氟化物,如吨-butylSF 3,difluorodibenzothiophene,PhSeF 3中,Ph 2 SEF 2,PHSF 5,p -MeC 6 ħ 4 SF 5,PhSeF 5和PhTeF 5。简要介绍了Ph 2 S(O)F 2与醇和H 2 O-HF玻璃系统的反应。

Novel processes for preparing arylsulfur pentafluorides are disclosed. Processes include reacting at least one aryl sulfur compound with a halogen and a fluoro salt to form an arylsulfur halotetrafluoride. The arylsulfur halotetrafluoride is reacted with a fluoride source to form a target arylsulfur pentafluoride.

Industrial methods for producing arylsulfur pentafluorides are disclosed. Methods include reacting arylsulfur halotetrafluoride with hydrogen fluoride in the absence or presence of one or more additives selected from a group of fluoride salts, non-fluoride salts, and unsaturated organic compounds to form arylsulfur pentafluorides.
