Abstract

To our knowledge, these chloroindate catalyst systems have not been utilised for alkylation of hydroxyarenes or any other active arenes (apart from our recent patent). 23 We report here that the same class of ionic liquids derived from 1,1-dialkylimidazolium chlorides and indium(III) chloride can be successfully utilised for alkylation of hydroxyarenes (see Scheme 1, 1–3) to produce valuable products with excellent selectivity and conversions. ... Although the exact speciation of ...
