The cyanate ion is an anion consisting of one oxygen atom, one carbon atom, and one nitrogen atom (OCN⁻), in that order, and possesses 1 unit of negative charge, borne mainly by the nitrogen atom. In organic compounds the cyanate group is a functional group. An ion is an atom, group of atoms, or subatomic particle with a net electric charge. ... An anion is an ion with negative charge. ...

Electric charge is a fundamental conserved property of some subatomic particles, which determines their electromagnetic interactions. ... Benzene An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and elementary carbon. ... In organic chemistry functional groups are specific groups of atoms within molecules, that are responsible for the characteristic chemical reactions of those molecules. ...

The cyanate ion is an ambident nucleophile in nucleophilic substitution because it can react to form an alkyl cyanate R-OCN (exception) or an alkyl isocyanate R-NCO (rule). Aryl cyanates (C₆H₅OCN) can be formed by a reaction of phenol with cyanogen chloride (ClCN) in the presence of a base. In chemistry, a nucleophile (literally nucleus lover as in nucleus and phile) is a reagent that forms a chemical bond to its reaction partner (the electrophile) by donating both bonding electrons [1]. Because nucleophiles donate electrons, they are by definition Lewis bases (see acid-base reaction theories). ... In chemistry, nucleophilic substitution is a class of substitution reaction in which an electron-rich nucleophile attacks a molecule and replaces a group or atom, called the leaving group. ... Isocyanate is the chemical group of atoms -N=C=O (1 nitrogen, 1 carbon, 1 oxygen), as opposed to cyanate, -O-C≡N, which is formed from cyanogen in the normal -ate manner. ... In the context of organic molecules, aryl refers to any member of the set of functional groups or substituents that are derived from a simple aromatic ring. ... Phenol, also known under an older name of carbolic acid, is a colorless crystalline solid with a typical sweet tarry odor. ... Cyanogen is a chemical compound (CN)2. ...

Cyanates are salts of cyanic acid for example potassium cyanate (KNCO). Cyanic acid is a colourless poisonous liquid with a boiling point of 23. ... Potassium cyanate or potassium isocyanate is an inorganic compound and the potassium salt of cyanic acid with the chemical formula of KOCN (also: KCNO). ...

The 'cyanate ion is relatively non-toxic in comparison to cyanides. Use of this fact is made in cyanide decontamination processes where a permanganate oxidation converts toxic cyanide to cyanate.
