Abstract
Here, we present an innovative approach to achieve Minisci-type alkylation of cyclic N-ketimines, enabling access to a diverse range of valuable alkylated sulfonyl ketimines via iron hydride hydrogen atom transfer. More than 35 examples are shown with a wide range of substrates. Additionally, this system is easy to operate and can be efficiently scaled up. Mechanistic investigations revealed that the alkyl radical process involved and the air acts as the sole oxidant in this system.
期刊介绍：
Advanced Synthesis & Catalysis (ASC) is the leading primary journal in organic, organometallic, and applied chemistry.
The high impact of ASC can be attributed to the unique focus of the journal, which publishes exciting new results from academic and industrial labs on efficient, practical, and environmentally friendly organic synthesis. While homogeneous, heterogeneous, organic, and enzyme catalysis are key technologies to achieve green synthesis, significant contributions to the same goal by synthesis design, reaction techniques, flow chemistry, and continuous processing, multiphase catalysis, green solvents, catalyst immobilization, and recycling, separation science, and process development are also featured in ASC. The Aims and Scope can be found in the Notice to Authors or on the first page of the table of contents in every issue.
