Cobalt-catalysed acyl silane directed ortho C–H functionalisation of benzoyl silanes

Chemical Communications, Год журнала: 2022, Номер 58(90), С. 12604 - 12607

Опубликована: Янв. 1, 2022

Acyl silanes can be engaged as weakly coordinating directing groups in cobalt catalysed C–H functionalisation reactions to prepare benzoyl that are highly amenable subsequent synthetic manipulations yet inaccessible via existing methods.

Electron‐Rich Oxycarbenes: New Synthetic and Catalytic Applications beyond Group 6 Fischer Carbene Complexes

Angewandte Chemie, Год журнала: 2023, Номер 135(13)

Опубликована: Янв. 3, 2023

Abstract Oxycarbenes have emerged as useful intermediates in synthetic chemistry. Compared to the widely studied oxycarbene metal complexes bearing Group 6 metals, and catalytic applications of oxycarbenes beyond Fischer carbene are less explored because difficulty controlling their reactivity need use a stoichiometric amount presynthesized complex starting material. This Minireview summarizes early late‐transition‐metal highlights recent advances free reactions transition‐metal‐catalyzed involving oxycarbenes. We hope this will inspire further developments emerging area.

Metal‐Free Activation of the Donor – Acceptor Cyclopropanes: Protic Acids, Bases, and Thermal Reactions

Опубликована: Фев. 16, 2024

In the past decades, remarkable progress has been made in field of metal-free activation donor–acceptor (D−A) cyclopropanes. This chapter focuses on introducing various strategies for C─C bond cleavage D−A cyclopropanes by means protic acids, non-metal Lewis bases, thermal reactions, and so on. Four main sections based different modes activation, including electrophilic nucleophilic catalyst-free D–A via radical process, are reviewed discussed.
