Dramatic Influence of Ionic Liquid and Ultrasound Irradiation on the Electrophilic Sulfinylation of Aromatic Compounds by Sulfinic Esters

Autor: Ngoc-Lan Thi Nguyen, Hong-Thom Vo, Fritz Duus, Thi Xuan Thi Luu

Publikováno v: Molecules, Vol 22, Iss 9, p 1458 (2017)

The sulfinylation reaction of aromatic and hetero-aromatic compounds with sulfinic esters as electrophiles has been investigated in different ionic liquids and by means of different Lewis acid salts in order to get moderate to good yields of asymmetr
