A chiral iridium(I) diphosphine complex efficiently catalyses the unprecedented ortho-alkylation of phenol with norbornene in the absence of solvent leading to the formation of one and two C-C bonds.
Abstract C-Alkylations of phenol with 1-chloro and 1-bromoadamantane, 2-bromoadamantane, cyclohexyl bromide and exo-2-bromonorbornane, and C-alkylations of para-substituted phenol derivatives with 2-bromoadamantane are described.
