Phenyl isocyanate preparation
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 has to be handled with care. … See more PhNCO is a planar molecule, according to X-ray crystallography. The N=C=O linkage is nearly linear. The C=N and C=O distances are respectively 1.195 and 1.173 Å. See more • Phenyl Isocyanate Data Sheet See more WebThe isocyanate adds water in a nucleophilic addition step to yield a carbamic acid (aka urethane ). The carbamic acid spontaneously loses CO 2, yielding the amine product. Variations [ edit] Several reagents can be substituted for bromine.
