Phenylthiocarbonyl isocyanate

Phenylthiocarbonyl isocyanate reacts similarly with carbodiimides to give [2+4] cycloadducts 217. From N-phenyl-N -cyclohexylcarbodiimide and phenyl-thiocarbonyl isocyanate two isomeric [2+4] cycloadducts are obtained. Aliphatic thiocarbonyl isocyanates react similarly to give [2+4] cycloadducts.
