General Description

Imidodisulfuryl chloride is a chemical compound with the molecular formula S2(NH)2Cl2. It is an inorganic compound that is formed by replacing the oxygen atoms in sulfate ions with chlorine atoms. Imidodisulfuryl chloride is a colorless liquid with a pungent odor, and it is highly reactive. It is commonly used as a reagent in organic synthesis, particularly in the conversion of alcohols to alkyl chlorides. It is also used in the production of agrochemicals and pharmaceuticals. Imidodisulfuryl chloride must be handled and stored with care, as it is corrosive and can cause severe skin and eye irritation.

Effect of N-substituents on protonation chemistry of trichlorophosphazenes

The protonation chemistry of trichlorophosphazene (R1-N=PCl3) with sulfonic acids (R2SO3H) was found to be affected by the N-substituents R1, yielding bis(sulfonyl)imides containing both R1 and R2, and mixed sulfonylphosphonyl imides containing either R1 or R2. In the formation of the latter a hitherto unobserved chemistry occurred. An intramolecular 'imine SN2' mechanism was proposed to rationalize the reactions observed. (C) 2000 Elsevier Science S.A.

METHOD FOR PRODUCING TRIFLUOROMETHANESULFONYL IMIDE OR ITS SALT

The present invention relates to trifluoromethanesulfonyl imide or a method of producing salt thereof. More specifically, the method comprises: a first process in which the organosilicon nitrogen compound is dissolved in an organic solvent, and chlorosulfonic acid (ClSO_3H) or dichlorosulfone (ClSO_2Cl) is added and reaction is conducted; and a second process in which the compound obtained through the first process is dissolved in an organic solvent, an inorganic base containing lithium, sodium, potassium or cesium or an organic base is added and reaction is conducted, and tetrahalogen methane (CX_4) is added thereto and reaction is conducted. According to the present invention, the method has effects of: producing stable and high-quality trifluoromethanesulfonyl imide and the salt thereof by using the safe organosilicon nitrogen compound without amine gas or inorganic amine; and being capable of mass producing industrially high-purity products.
