摘要：

A half sandwich helping: Cationic rare-earth alkyl species generated from half-sandwich rare-earth dialkyl complexes and [Ph3C][B(C 6F5)4] can serve as unique catalysts for the C-H regioselective alkylation of anisoles with alkenes. The reaction affords either ortho-monoalkylated derivatives or products substituted at the benzylic position, depending on the substrate chosen. Copyright © 2012 WILEY-VCH Verlag GmbH & Co.
