Benzenesulfonyl isocyanate reacts with ethanol and phenol to yield normal urethan productsBenzenesulfonyl 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 Benzenesulfonyl isocyanate reacts with ethanol and phenol to yield normal urethan products Benzenesulfonyl isocyanate was used in synthesis of sterically hindered derivatives of phenols and alcohols.
