Phosgene → HCID 13645990, compound

Participants

Reaction Steps

A solution of 2-(methylselenyl)benzenesulfonamide (6.25 g, 25.0 mmol), n-butyl isocyanate (2.81 mL, 25.0 mmol), and 1,4-diaza[2.2.2]bicyclooctane (0.1 g, 1 mmol) in mixed xylenes was heated at reflux for 0.5 hours. Phosgene was then added at such a rate that the internal temperature stayed at 133° C. or above. When consumption of phosgene ceased, the solution was cooled to room temperature and then filtered under nitrogen. Rotary evaporation gave 2-(methylselenyl)benzenesulfonyl isocyanate as a brown oil (8.8 g). This was used immediately without further purification or characterization.
