Ir(III)-Catalyzed Carbocarbation of Alkynes through Undirected Double C-H Bond Activation of Anisoles

Journal of the American Chemical Society, 2018
A novel, electron-deficient cyclopentadienyl iridium(III) catalyst enables sequential cleavage of arene C(sp2)-H and methoxy C(sp3)-H bonds of anisoles, generating reactive metalacycles that insert difluoroalkynes to afford chromenes under mild reaction ...

Tuning Reactivity and Site Selectivity of Simple Arenes in C–H Activation: Ortho-Arylation of Anisoles via Arene–Metal π-Complexation

Journal of the American Chemical Society, 2014
Current approaches to achieve site selectivity in the C–H activation of arenes involve the use of directing groups or highly electron-poor arenes. In contrast, simple arenes, such as anisole, are characterized by poor reactivity and selectivity.

Nonnative Thiol and Aniline Methylation, Including Enantioselective Dithiol Desymmetrization, by Multicomponent Cobamide-Dependent Methyltransferases Using Unactivated Methyl Donors. [PDF]

Angew Chem Int Ed Engl
Mixed MtaABC/MtgABC methyltransferase systems were developed for non‐native thiol and aniline methylation using the unactivated methyl donors methanol and glycine betaine. The platform enabled site‐selective and enantioselective methylation with turnover number up to 6000, representing the first enantioselective non‐native catalysis by cobamide ...

High‐Performance Self‐Powered Perovskite Photodiodes for Blue‐Light Detection Using Anisole‐Assisted Precursor Engineering [PDF]

Small, Volume 22, Issue 62, 6 November 2026.
Anisole‐assisted precursor engineering provides a simple route to high‐quality perovskite films for self‐powered blue‐light photodetection. Anisole promotes grain growth and suppresses pinholes, reducing dark current while improving external quantum efficiency and detectivity.

Synthesis and reactivity of aliphatic sulfur pentafluorides from substituted (pentafluorosulfanyl)benzenes

Beilstein Journal of Organic Chemistry, 2016
Oxidation of 3- and 4-pentafluorosulfanyl-substituted anisoles and phenols with hydrogen peroxide and sulfuric acid provided a mixture of SF5-substituted muconolactone, maleic, and succinic acids.

Conversion of Alcohols into Amides Using Alumina-Methanesulfonic Acid (AMA) in Nitrile Solvents [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 1999
The reaction of tertiary, secondary and benzylic alcohols with different nitriles in the presence of alumina-methanesulfonic acid (AMA) as a new reagent affords the corresponding amides in good yields (Table 1, 2).

Regioselective Intramolecular Oxidation of Phenols and Anisoles by Dioxiranes Generated in Situ

, 2016
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.

Lanthanide Centered and Circular Polarized Luminescence (CPL) From Tb(III) Complexes Made From Structurally Simple Methoxy-Phenyl and Phenol-Derived Pyridyldiamide (pda) Ligands. [PDF]

Chemistry
The development of chiral pda derived methoxy ligands L1a [1(R,R)] and L1b [1(S,S)], along with their phenol derivatives L2a [2(R,R)] and L2b [2(S,S)], and their respective Tb(III) complexes is described. These Tb‐complexes exhibited Tb(III)‐centered emission upon and their chiroptical properties were probed by using both CD and CPL spectroscopy ...

Asymmetric Approach toward Chiral Cyclohex-2-enones from Anisoles via an Enantioselective Isomerization by a New Chiral Diamine Catalyst

Journal of the American Chemical Society, 2012
A 3-step asymmetric approach toward the optically active chiral cyclohex-2-enones from anisoles has been developed. The crucial asymmetric induction step is an unprecedented catalytic enantioselective isomerization of β,γ-unsaturated cyclohex-3-en-1-ones
