Undirected, Homogeneous C–H Bond Functionalization: Challenges and Opportunities [PDF]

open access: yesACS Central Science, 2016
The functionalization of C-H bonds has created new approaches to preparing organic molecules by enabling new strategic "disconnections" during the planning of a synthetic route. Such functionalizations also have created the ability to derivatize complex molecules by modifying one or more of the many C-H bonds.

Synthesis of Benzo[4,5]thiazolo[2,3-c][1,2,4]triazole Derivatives via C-H Bond Functionalization of Disulfide Intermediates [PDF]

open access: yesMolecules, 2022
Many nitrogen- and sulfur-containing heterocyclic compounds exhibit biological activity. Among these heterocycles are benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles for which two main synthetic approaches exist.

Site-Selective C─H Bond Functionalization of Sugars. [PDF]

open access: yesAngew Chem Int Ed Engl
AbstractNon‐typical C‐functionalized sugars represent a prominent yet hardly accessible class of biologically‐active compounds. The available synthetic methodologies toward such sugar derivatives suffer either from an extensive use of protecting groups, requiring long and laborious synthetic manipulations, or from limited predictability and ...

In-situ noncovalent interaction of ammonium ion enabled C–H bond functionalization of polyethylene glycols [PDF]

open access: yesNature Communications
The noncovalent interactions of ammonium ion with multidentate oxygen-based host has never been reported as a reacting center in catalytic reactions. In this work, we report a reactivity enhancement process enabled by non-covalent interaction of ammonium

Transition-metal-free electrochemical-induced active C(sp3)-H functionalization

open access: yesGreen Chemistry Letters and Reviews, 2023
Direct C–H bond functionalization is the most effective technique to construct C–X (X = C, N, O, S, etc.), which could simplify the conventional synthesis methods.

C–H bond functionalization reactions enabled by photobiocatalytic cascades

open access: yesGreen Synthesis and Catalysis, 2021
Light may participate in biocatalytic processes either by direct light-induced biocatalysis or by cascading light-induced chemical reactions with biocatalytic ones, which are acknowledged as photocatalysis.
