Chemical Communications, 2012 As the aluminate base [LiAl(TMP)(2)(iBu)(2)] 1 displays halogen tolerance towards substituted aromatics, 4-halo-anisoles have been ortho-aluminated and electrophilically quenched to form synthetically useful multi-heterohalogenated anisoles, with the Al ...

Direct ortho Arylation of Anisoles via the Formation of Four-Membered Lithiumcycles/Palladacycles
Synlett : Accounts and Rapid Communications in Synthetic Organic Chemistry, 2017 We report here our latest discovery on the directed lithiation and palladium-catalyzed arylation of anisoles. During this research, the formation of a four-membered lithiumcycle followed by transmetalation to the corresponding palladacycle has been ...

Regioselective intramolecular oxidation of phenols and anisoles by dioxiranes generated in situ
Journal of Organic Chemistry, 2000 A novel method for regioselective oxidation of phenols and anisoles has been developed in which dioxiranes, generated in situ from ketones and Oxone, oxidize phenol derivatives in an intramolecular fashion.

Organic Letters, 2022
An enantioselective insertion of a carbene into the Csp2-H bond of anisole derivatives has been accomplished using an achiral gold complex and a chiral phosphoric acid as the catalytic system, providing a novel protocol for the synthesis of chiral α,α ...

Synlett, 1999 Anisoles 1, reacting with AlCl3 and PCl3 with appropriate reagent ratios, give, in good yields, the corresponding diaryl methylphosphonates 2 or the methylphoshinates 3b,c and the methylphosphine oxides 4b,c. This unexpected in situ methylphosphorylation
