Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phenyl isocyanate | HCID 7672 | — |
| Reactant | Allylamine | HCID 7853 | — |
| Solvent | Benzene | HCID 241 | — |
| Product | 1-Allyl-3-phenylurea | HCID 5147890 | 95% |
Reaction Steps
A solution of 100 g (0.84 mole) phenylisocyanate in 50 ml of benzene was added dropwise over a period of 30 minutes to a stirring solution of 60 g (1.05 mole) allyl amine in 2 liters of benzene. The mixture was stirred overnight and suction filtered yielding 120 g (95% yield) of 1-phenyl-3-allyl urea with a melting point of 112°-113°. This material was also characterized by IR and nmr analysis.
