CLEAR COLOURLESS LIQUID | [Uses]
Benzenesulfonyl isocyanate was used in synthesis of sterically hindered derivatives of phenols and alcohols. It was also used in the reaction of semi crystalline poly(ether ether ketone) films with carbonyl selective reagents to produce modified film samples. | [General Description]
Benzenesulfonyl isocyanate reacts with ethanol and phenol to yield normal urethan products. | [Reactivity Profile]
Benzenesulfonyl Isocyanate is a derivatizing agent for alcohols and phenols; used to convert (thio)carbonyl compounds to imino derivatives; used in the preparation of β-lactams and a wide variety of heterocycles via cycloaddition reactions.
| [Precautions]
lachrymator; corrosive; use only in a fume hood; wear protective gloves and preferably a NIOSH-approved respirator. All transfers and reactions should be carried out under anhydrous conditions. Store in a cool dry place, taking care to avoid contamination with protic, basic, or organometallic materials, as these may induce polymerization.
