Benzyl bromide is an organic compound with the formula C 6 H 5 CH 2 Br. The molecule consists of a benzene ring substituted with a bromomethyl group. It is a colorless liquid with lachrymatory properties. The compound is a reagent for introducing benzyl groups. [3] [4]
CAPS is the common name for 3-(Cyclohexylamino)-1-propanesulfonic acid, a chemical used as buffering agent in biochemistry. The similar substance N-cyclohexyl-2-hydroxyl-3-aminopropanesulfonic acid (CAPSO) is also used as buffering agent in biochemistry. Its useful pH range is 9.7-11.1.
Cyclohexylbenzene (or phenylhexamethylene, as it was initially called) was first obtained in 1899 by Markovnikov's student Nikolay Kirsanov (1874–1921). [1] He used a Friedel–Crafts alkylation of benzene with cyclohexyl chloride: [2]
The Hofmann rearrangement (Hofmann degradation) is the organic reaction of a primary amide to a primary amine with one less carbon atom. [1] [2] [3] The reaction involves oxidation of the nitrogen followed by rearrangement of the carbonyl and nitrogen to give an isocyanate intermediate.
