Phenyl isocyanate is an organic compound typically abbreviated PhNCO. 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 should be handled in the fumehood.

Characteristic of other isocyanates, it reacts with amines to give ureas . [1] Similarly, reacts with alcohols to form carbamates .

It is used in addition with triethylamine to activate nitro groups to undergo (C,O) 1,3-dipolar cycloaddition (as opposed to O,O). The nitro group (RCH2NO2) is converted to RCNO in the reaction, with CO2 as one of the by products. [2]
