Phenylisocyanate
WebPhenylisothiocyanate and phenylisocyanate adds to 2-amino-2-thiazoline ( 79) to give the corresponding adducts 〈86JOC1910〉. The reaction of ( 79) with phenyl isothiocyanate resulted in almost exclusive formation of thiocarbanilide ( 80 ), only a small amount of thiourea ( 81) being obtained. 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
