The Lewis acidity and polarity of LiClO 4 /Et 2 O as a reaction medium are sufficient to cause the allylation of trisubstituted quinones with allyltrimethylsilane. A radical process with an electron‐transfer step from a quinone/allylsilane charge‐transfer complex is postulated for the reaction sequence. One product is 1 , depicted to the right (R 1 = CH 3 , R 2 = R 3 = OCH 3 ).
