Sulfamide (IUPAC name: sulfuric diamide) is a compound with the chemical formula SO 2 (NH 2) 2 and structure H 2 N−S(=O) 2 −NH 2. Sulfamide is produced by the reaction of sulfuryl chloride with ammonia. Sulfamide was first prepared in 1838 by the French chemist Henri Victor Regnault. [2]
Sulfanilamide (also spelled sulphanilamide) is a sulfonamide antibacterial drug. Chemically, it is an organic compound consisting of an aniline derivatized with a sulfonamide group. [ 1 ] Powdered sulfanilamide was used by the Allies in World War II to reduce infection rates and contributed to a dramatic reduction in mortality rates compared to ...
Many important drugs contain the sulfonamide group. [1] A sulfonamide (compound) is a chemical compound that contains this group. The general formula is R−SO 2 NR'R" or R−S(=O) 2 −NR'R", where each R is some organic group; for example, "methanesulfonamide" (where R = methane, R' = R" = hydrogen) is CH 3 SO 2 NH 2.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
In organosulfur chemistry, sulfinamide is a functional group with the structure R−S(O)−NR 2 (where R = alkyl or aryl). [1] This functionality is composed of a sulfur - carbon ( S−C ) single bond , a sulfur- nitrogen ( S−N ) single bond , and a sulfur-oxygen (S-O) bond (see Sulfoxide for the nature of this bond) [ 2 ] .
General chemical structure of a sulfanilide. In organic chemistry, a sulfonanilide group is a functional group found in certain organosulfur compounds.It possesses the chemical structure R−S(=O) 2 −N(−C 6 H 5)−R', and consists of a sulfonamide group (R−S(=O) 2 −NR'R") where one of the two nitrogen substituents (R' or R") is a phenyl group (C 6 H 5).
Sulfanilic acid can be produced by sulfonation of aniline with concentrated sulfuric acid. [5] This proceeds via phenylsulfamic acid; a zwitterion with a N-S bond. Eugen Bamberger originally proposed a mechanism involving a series of intramolecular rearrangements, with phenylsulfamic acid forming orthanilic acid, which rearranged to sulfanilic acid on heating.
Sulfenamides have been characterized by X-ray crystallography.The S-N bond in sulfenamides is a chiral axis that leads to formation of diastereomeric compounds. The existence of these distinct stereoisomers is due to the formation of a partial double bond between either sulfur or nitrogen's lone pair and the other atom's antibonding orbitals. [1]
