Phenyl isocyanate → HCID 19390266, compound

Participants

Reaction Steps

5.00 g (42.0 mmol) of p-aminostyrene (99% Tokyo Kasei) was added to a 250 ml round bottom flask. After ten minutes of mixing, 5.00 g (42.0 mmol) of phenyl isocyanate (99% Aldrich) was added dropwise. Within seconds, a yellow precipitate formed. Chloroform (20 ml) was added to aid stirring. The precipitate was filtered to remove the reaction liquid, then washed with 20 ml of chloroform resulting in a pale yellow powder (8.60 g, 86.0 % crude yield, mp=213° C.).
