Thia-Fries rearrangement of aryl triflinates to trifluoromethanesulfinylphenols
摘要:
Aryl trillinates are transformed to trifluoromethanesulfinylphenols in the presence of aluminum trichloride in dichloromethane at room temperature according to a thia-Fries rearrangement process. Rigorous exclusion of oxygen is necessary in order to avoid the formation of 2,2'-dihydroxybiaryls as secondary products. (C) 2003 Elsevier Science B.V. All rights reserved.
