Ultrasound promoted para-selective nitration of phenols in ionic liquid.
Ultrasound promoted nitration of phenol and substituted phenols using ferric nitrate and Clayfen respectively in the ionic liquid ethyl ammonium nitrate has exhibited significant enhancement in rates of reaction as well as high para selectivity as compared to corresponding reactions performed without ultrasound.
