摘要:
A new method for preparing fluorinated phenylsulfur pentafluorides is disclosed. A fluorinated phenylsulfur halotetrafluoride is reacted with SbFnClm and SbF3 to form a fluorinated phenylsulfur pentafluoride.
摘要:
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.

摘要:
Ambient-temperature molten salts of formula (I): wherein Y+ is a cation selected from the group consisting of an ammonium ion, a sulfonium ion, a pyridinium ion, a(n) (iso)thiazolium ion, and a(n) (iso)oxazolium ion that may be optionally substituted with C1-10 alkyl and/or C1-10 alkyl having ether linkage, provided that the above cation has at least one substituent of —CH2Rf1 or —OCH2Rf1 (wherein Rf1 is C1-10 perfluoroalkyl); Rf2 and Rf3 are independently C1-10 perfluoroalkyl or may together form C1-4 perfluoroalkylene; and X is —SO2- or —CO—.

A process for preparing a N,N'-difluorodiazoniabicycloalkane salt of the formula: ##STR1## by reacting a corresponding diazabicycloalkane or diazabicycloalkane Br.o slashed.nsted acid salt and fluorine in the presence of a Br.o slashed.nsted acid or in the presene or absence of a base, by reacting a corresponding N,N'-difluorodiazoniabicycloalkane salt and an acid or salt, by reacting a corresponding diazabicycloalkane and fluorine in the presence of a Br.o slashed.nsted acid and then reacting an intermediate product and an acid or salt, or by reacting a corresponding diazabicycloalkane Br.o slashed.nsted acid salt and fluorine in the presence or absence of a base and then reacting an intermediate product and an acid or salt.
摘要:
The present invention relates to a process for generating an energy such as electricity, a device therefor and a compound having a N--F bond and generating an energy such as electricity and a battery using the compound, and can provide a process for generating energy such as electricity by the use of materials for an active material for a battery, an electrolyte, or the like, which is handled easily and is superior in environmental acceptability.
摘要:
A substituted N-fluoropyridiniumsulfonate of the formula: ##STR1## in which R.sup.1 is a hydrogen atom, a halogen atom or a C.sub.1 -C.sub.4 alkyl or haloalkyl group, and R.sup.2 is a C.sub.1 -C.sub.4 alkyl or haloalkyl group, which is an effective fluorinating agent.
摘要:
A pyridine-compound is reacted with fluorine together with a Bronsted acid-compound or Lewis acid to form a N-fluoropyridinium salt which is very active to other compounds but is very selective for the preparation of a desired product and this product is very useful for a fluorine-introducing agent which makes it useful for the preparation of fluoro-compounds such as thyroid inhibitor.
