3,4-Dichlorophenyl isocyanate is a chemical compound used as a chemical intermediate and in organic synthesis.It is a solid, and ranges in colour from white to yellow. It is an irritant for tissues including eyes and mucous membranes, and inhalation of dust from the chemical is poisonous. [1]
The molecule consists of a phenyl ring attached to the isocyanate functional group. It is a colourless liquid that reacts with water. Phenyl isocyanate has a strong odor and tearing vapours, therefore it has to be handled with care. Characteristic of other isocyanates, it reacts with amines to give ureas. [2]

Allyl thiocyanate isomerizes to the isothiocyanate: [4] CH 2 =CHCH 2 SCN → CH 2 =CHCH 2 NCS. Isothiocyanates can be prepared by treating organic dithiocarbamate salts with lead nitrate or tosyl chloride. [5] [6] Synthesis of phenyl isothiocyanate. Isothiocyanates may also be accessed by the fragmentation reactions of 1,4,2-oxathiazoles. [7]
