4-Chlorophenyl isocyanate is used in the preparation of isothiocyanates. Aryl isocyanates undergo [2+2] cycloaddition reactions with dihydrofuran to give bicyclic β-lactams in high yield.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
4-Chlorophenyl isocyanate is used in the preparation of isothiocyanates. Aryl isocyanates undergo [2+2] cycloaddition reactions with dihydrofuran to give bicyclic ß-lactams in high yield.
Solubility
Hydrolyzes in water.
Notes
Keep container tightly closed. Store away from oxidizing agents.
